Certainly! Here are the answers to the questions:
1. The term that describes the tendency of an object that is moving to keep moving is (c) inertia. Inertia is the property of matter that causes it to resist any changes in its motion.
2. The force of resistance that makes a rolling ball stop is (a) friction. Friction is the force that opposes the motion of an object when it is in contact with another surface.
3. When a bullet is fired from a gun, the force that the bullet exerts back on the gun is known as (b) reaction force. According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. In this case, as the bullet is propelled forward, it exerts an equal force in the opposite direction on the gun.
I hope this helps clarify the concepts for you! If you have any more questions or need further explanations, feel free to ask.
