It remains constant.
It becomes zero.
#4

What is the term for the property of an object to resist changes in its state of motion?

Acceleration
Inertia
Velocity
Momentum
#5

In experimental analysis of motion, what does the term 'acceleration' represent?

Change in position over time
Change in velocity over time
