# How to Calculate Velocity Using the v = S/T Formula

Velocity is a vector quantity, meaning it includes both magnitude (speed) and direction. Examples of velocity include the speed of a car moving down the road or a rocket traveling into space.

The magnitude of velocity is shown on a position-versus-time graph as the slope of the line. The direction of velocity is shown as a arrow from left to right.

## Definition

Velocity is the amount of change in an object’s position divided by the time it takes to travel that distance. It is a vector quantity, meaning it requires both magnitude (speed) and direction.

Displacement is the actual distance the object has traveled from its starting point. The instantaneous velocity of an object is the displacement divided by the time, or v = S/T. This formula is also used to calculate average velocity, which is the average speed over a given length of time.

If you know the initial velocity and constant acceleration of an object, then you can find its position and velocity at any point in time by integrating: v(t) = v(0) + a(t). This formula is particularly useful for solving problems related to transportation, such as worktimetables or train schedules. It can also be used to determine escape velocity, which is the minimum speed required to overcome the gravitational pull of a planet or other massive body.

## Formula

Velocity is a vector quantity that measures the direction and speed of motion. It is calculated as the derivative of displacement with respect to time and measured in metres per second (m/s). In linear motion, there are two types of velocity: instantaneous velocity and average velocity.

The instantaneous velocity is the slope of the position function v(t) versus time. This can be determined on a graph by plotting the points x(t) and v(t). The slope of the tangent line at the point ti is the instantaneous velocity.

To find the average velocity of an object, you divide the displacement divided by the change in time. The magnitude of the average speed must be greater than or equal to the magnitude of the displacement. This is different from the average speed of a line that has changed direction, which depends on the magnitude of the displacement and not the direction.

## Units

Velocity is a vector quantity meaning it has direction and is derived from displacement divided by time. Its unit is meter per second (m/s).

Speed is a scalar quantity which only gives the rate of movement and not the direction. For example, a train traveling at 50 kilometers per hour has the same speed whether it is traveling north or south.

Another important difference between the two is that velocity is a ratio between an object’s change in position and its change in time. This makes it different from distance which is a measure of the change in position without any reference to time.

The Initial Velocity is the velocity an object had when it started to move. This is usually represented by the symbol v0. The Final Velocity is the velocity an object has at the end of its motion. This is usually represented by the symbol fv. It can be determined by dividing the total distance traveled by the total amount of time it took to travel that distance.

## Examples

The formula v = s/t gives you velocity as a function of displacement and time. Displacement is the distance the object has traveled from its starting point, and time is the amount of time it has taken to travel that distance.

The difference between speed and velocity is that velocity includes direction while speed does not. For example, an object moving in a circle has constant speed but changes direction in the process. This makes it difficult to determine its average speed because it doesn’t stay the same for long periods of time.

If you drop a book from the top of your dorm building, it has an initial velocity when it leaves your hand and accelerates downward until it reaches its final velocity. This is called non-uniform acceleration. The initial velocity can be determined by using the equation v(t) = (d + s)/t. The sign of v(t) will indicate its direction, either positive or negative.

# Geometry Unit 7

Six lessons compose geometry unit 7. Students start by reviewing the Pythagorean Theorem and its converse. They then move on to study special right triangles, and trigonometric ratios. Using their newfound knowledge of triangle similarity postulates and theorems, they begin to calculate arc lengths from given sector areas and central angles.

## Circles

A circle is a 2-dimensional closed shape that has curved sides. Students learn the definition of a circle, formulas for radius and circumference, and problem-solve related to circles. They also study the properties of chords, secants and tangents within a circle.

Circles are a key topic for developing students’ understanding of relationships between angles and segments. They will analyze inscribed and circumscribed angles, find arc lengths for circles of different sizes, and solve problems relating to central angle, radius, and arc area.

Using the information from the previous lesson, students will investigate the relationship between a radius and a diameter. They will find that a radius is half the diameter and the distance between the centre and the outermost point of the circle, known as the circumference, is double the radius (see figure below).

## Right Triangles

A right triangle is a two-dimensional figure with one right angle and three sides. It has a vertex and a hypotenuse, or longest side. The legs are opposite or adjacent to the vertex. The legs can be measured by their lengths, or their angles can be identified and classified as acute, obtuse, or straight.

Students learn about the Pythagorean Theorem and how the lengths of the three sides relate. They also learn that when they know the length of only two sides, they can use sine, cosine, and tangent values to find the remaining side.

Students use tables of known triangle dimensions to compare the sizes of different right triangles. They are challenged to think about unknown angle measures and how they might be solved based on the patterns they have noticed in these tables.

## Trigonometric Ratios

In geometry, the ratios of a triangle’s sides to its angles are called trigonometric functions or trig ratios. There are six trigonometric ratios: sine (sin), cosine (cos), tangent (tang), secant, and cosecant (or csc). Students can recall these with the mnemonic SOHCAHTOA.

Students will learn how to choose a trig ratio given an angle and side of a right triangle. They will also see that similar triangles are formed when all three trig ratios are equal.

Today’s Check Your Understanding question asks students to use what they have learned about trig ratios to determine whether two triangles are similar. The question is meant to help students realize that the information they were given in Unit 6 about the ratios of a triangle’s side lengths and angles is encoded in those ratios—they just have to know which trig ratios to select! This is a preview of what they will learn next in lesson 7.4..

## Similarity

Students informally understand similarity before starting geometry, but it is formally explored during this unit. Triangle similarity postulates and theorems are analyzed along with side-splitting, proportional medians, angle bisectors, and altitudes.

Two triangles are similar if all corresponding pairs of angles are congruent and the sides that include those angles are proportional to one another. Students also learn how to use transformations to show that a figure is similar to another figure.

# Lines and Angles

Lines and angles are one of the basic concepts in geometry. It is important to understand these concepts to build other more complex ideas.

A line is a straight one-dimensional figure that extends infinitely in both directions. An angle is a figure formed by two rays with a common endpoint, called the vertex.

## Lines

Lines and angles are one of the most important elements that form the foundation for geometry. A line is a figure that extends infinitely in both directions, and an angle is a shape formed when two lines intersect. There are different types of lines and angles, such as parallel lines and perpendicular lines, and each has its own set of properties. The various properties of lines and angles are explored in this lesson through the use of real-life examples and logical reasoning.

A line is made up of an endless number of closely spaced points. It has no width or depth, and is a one-dimensional figure. It is represented on a plane by the linear equation ax + by = c, where a and b are constants.

When two straight lines intersect in a plane, the angle formed is called an angle of intersection. The two lines that make up the angle are known as its arms (sides), and the point where they meet is called the vertex. An angle is measured in degrees, which range from 0° to 360°.

There are many different types of lines and line segments in a plane. They can be categorized into several kinds based on their positioning with respect to each other. Two lines can be parallel if they never meet each other, or intersect at the same point. Lines can also be intersecting if they meet at distinct points, or transversal lines, which cut two or more lines at distinct points.

There are also many types of angles that can be formed between two lines. Adjacent angles are those that have a common side and a common vertex. For example, the angles OA and BOA are adjacent, since they have both a common arm and a common vertex. Vertically opposite angles are also formed when two lines intersect at a common point, or vertex. For example, the angles AB and AC are vertically opposite.

## Angles

Among the most important geometry concepts are lines and angles. Having a good understanding of how angles relate to one another can help you solve tricky questions on the GMAT, GRE and other competitive exams. Knowing the different types of angles and their relationships is also essential in understanding many other geometry concepts, such as triangles.

Two lines can intersect at any point and form an angle. This angle can be measured in degrees, with a full circle being 360°. In geometry, there are different types of angles, such as acute and obtuse. Each type of angle has its own name and characteristics. For example, an acute angle has a sharp point while an obtuse angle has a rounded point.

In addition to parallel and perpendicular lines, there are other types of line segments and angles. A line segment is a pair of end points with a definite length that extends between them. An angle is a figure formed by two rays that meet at a common point, called the vertex.

Whether an angle is congruent or not depends on how its vertices are located in relation to each other. If the vertices are on the same side of the line, they are congruent; if they are on opposite sides of the line, they are non-congruent. Additionally, the measure of an angle can be based on the number of rays that meet at its vertex.

When a pair of angles share a relationship with each other, they are referred to as related angles. For example, a pair of interior angles on the same side of a transversal are supplementary, while a pair of alternate interior angles is not. Additionally, the measure of an exterior angle is a combination of its measure and that of a corresponding interior angle.
