Question

the ball is moving because a(n)______is acting on the ball from point 1 to point 2.
a. mass
b. inertia
c. balanced force
d. unbalanced force

Explanation:

• Mass is a measure of the amount of matter in an object and does not directly cause motion.
• Inertia is the tendency of an object to resist changes in its state of motion. It is not a force that causes motion.
• Balanced forces result in no change in the object's motion (it will either remain at rest or move at a constant velocity).
• Unbalanced forces cause a change in the object's motion. When a ball moves down a ramp, gravity (an unbalanced force in this context as it overcomes friction to some extent) is acting on it to change its state from rest (at the top of the ramp) to motion.

Answer:

D. unbalanced force
