imagine a bowling ball sitting still on a table. which statement describes what it will do?
it will start to move on its own and then fall off.
it will accelerate on its own if left alone.
it will not move unless acted on by another force.

Explanation:

Acceleration is defined as the rate of change of velocity over time. According to Newton's first - law of motion, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. A bowling ball sitting still on a table is at rest and will remain so without an external force.

Answer:

For the first question: Acceleration equals the change in velocity divided by time.
For the second question: It will not move unless acted on by another force.
