Forces and Motion Concepts

What is a force in physics?

• A change in an object's position.

• Any kind of push or pull on an object.

• The speed and direction of an object's motion.

• A change in an object's velocity.

What happens to an object when the forces acting on it are balanced?

• The object speeds up.

• The object slows down.

• The object changes direction.

• The object remains still.

What causes an object to be set in motion?

• Unbalanced forces.

• Balanced forces.

• The absence of gravity.

• Its mass.

What is motion in physics?

• The force exerted by gravity.

• Any kind of push or pull on an object.

• A change in an object's position.

• The resistance an object has to a change in its state of motion.

What is required to change the state of motion of an object?

• An internal force

• An outside force

• A change in mass

• A change in temperature

How does increasing the force applied to an object affect its acceleration?

• It decreases the acceleration.

• It has no effect on acceleration.

• It increases the acceleration.

• It only affects the object's mass.

If an object has more mass, what is required to get it to move?

• Less force

• More force

• The same amount of force

• No force

What is the relationship between an action and its reaction?

• They are unrelated.

• They are equal in magnitude and opposite in direction.

• The reaction is always stronger than the action.

• The action is always stronger than the reaction.
