Q:
# What is the rate of change in velocity?

**The rate of change in velocity is called acceleration.** In the study of mechanics, acceleration is computed as it relates to time with a final unit of distance over time squared.

To compute the rate of change in velocity, or acceleration, of an object, the initial speed is subtracted from the final speed. This rate is then divided by the total length of the time period for the acceleration. For example, if a car traveled on a road for two hours and was going 30 mph at the beginning of the road and 60 mph at the end of the road, the rate of change is calculated by subtracting 30 from 60 to get a 30 mph difference. Then, the 30 miles per hour is divided by the total time of 2 hours for an acceleration result of 15 miles per hour squared.

Q:
## What is a velocity versus time graph used for?

A: A velocity versus time graph is used to evaluate the acceleration of an object. This is done by looking at the slope of the line on the graph. Full Answer >Filed Under: -
Q:
## Can the velocity of an object reverse direction while maintaining constant acceleration?

A: An object's acceleration is constant and downward due to the force of gravity In projectile motion, but the object's velocity reverses direction during the... Full Answer >Filed Under: -

## What is the definition of uniform velocity?

A: An object is said to have uniform velocity if the direction of motion and the rate at which the object changes its position is constant. In other words, an... Full Answer >Filed Under: -
Q:
## In what ways are acceleration and speed different?

A: Speed is rate of change in position, measured in distance over time, while acceleration is the change of speed in a particular direction over time. A car c... Full Answer >Filed Under:
