## What is constant speed?

An object is travelling at a steady or constant speed when its instantaneous speed has the same value throughout its journey. For example, if a car is travelling at a constant speed the reading on the car’s speedometer does not change.

## What do you need to find speed?

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

## What 2 factors are needed to calculate the velocity of an object?

Velocity is a physical vector quantity; both magnitude and direction are needed to define it.

## Which type of speed is found by looking at a speedometer?

A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards.

## Is speed the same as velocity?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.

## What two factors are measured to determine motion?

The two factors necessary for the description of motion (the speed) are the distance covered by the moving body and the time taken by the moving body to cover this distance.

## What are 2 ways that velocity can change?

An object can change velocity in a number of ways: it can slow down, it can speed up, or it can change direction. A change in speed, or a change in direction, or a change in both speed and direction means that the object has a change in velocity.

## What is the reading from the speedometer?

The speedometer of a car reveals information about the instantaneous speed of your car. It shows your speed at a particular instant in time. On the average, your car was moving with a speed of 25 miles per hour.

## What are the three differences between speed and velocity?

Speed can never be zero but the velocity can be positive, negative or zero. This is the difference between speed and velocity….Speed & Velocity.SpeedVelocitySpeed ascertains how fast a body moves.Velocity ascertains the object’s speed and the direction it takes while moving.3 more rows

## What is the difference between velocity speed and acceleration?

Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time.

## How do you calculate speed and velocity?

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
