Back

40 m/s²

Front

If a car's velocity changes from 10 m/s to 30 m/s in 5 seconds, what is its acceleration?

Back

4 m/s²

Front

A box sliding down an inclined plane attains a velocity of 27 m/s in 3 seconds from rest. Find the acceleration.

Back

9 m/s²

Front

What do the following symbols represent: Vi and Vf?

Back

beginning velocity and ending velocity

Front

Define acceleration in your own words.

Back

Acceleration is the change in velocity over time.

Front

What is the formula for calculating acceleration?

Back

a = (Vf - Vi) / t

Front

If an object is moving at a constant speed, what is its acceleration?

Back

0 m/s²

Front

What is the unit of acceleration in the SI system?

Back

meters per second squared (m/s²)

Front

How does negative acceleration (deceleration) affect an object's motion?

Back

It reduces the object's speed.
