# What Is a Velocity Versus Time Graph Used For?

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.

Continue ReadingA velocity versus time graph plots velocity on the y axis and time on the x axis. If the acceleration of an object is zero, the slope of the line is zero and a horizontal line is seen on the graph. If the acceleration of an object is positive, the slope of the line is positive and the line projects upward. If the acceleration of the object is negative, the slope of the line is negative and the line projects downward.

## What Is the Rate of Change in Velocity?

A: 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 dista... Full Answer >Filed Under: -
Q:
## Is Momentum a Vector Quantity?

A: Momentum is a vector quantity as it is the product of mass and velocity of an object. Mass is a scalar quantity but velocity is vector. In physics, the sym... Full Answer >Filed Under: -

## How Do You Know If Velocity Is Changing?

A: Because velocity is the rate of motion of an object in a specific direction, either an increase or decrease in the object's speed or a change in its direct... Full Answer >Filed Under: -
Q:
## How Fast Does an Object Fall?

A: Since a free-falling object only travels in one direction, its speed is equal to its velocity. The velocity of a falling object is equal to the downward ac... Full Answer >Filed Under:
