Which of the following best describes acceleration?
Change in velocity over time
Distance traveled over time
Change in position over time
The force applied to an object
A car is moving north at 20 m/s and then turns east at 20 m/s. What happens to the acceleration?
There is no acceleration because speed is constant
There is acceleration because velocity changes direction
Acceleration only occurs when speed increases
Acceleration only occurs when speed decreases
If an object has positive velocity and positive acceleration, what is happening?
The object is moving at a constant speed
The object is at rest and will remain at rest
The object is speeding up
The object is slowing down
When both acceleration is positive and velocity is negative, what does that mean?
The object is speeding up
The object is slowing down
The object is moving at constant speed
The object has stopped
