What is a force?

• A type of energy

• A push or pull on an object

• The speed of an object

• The mass of an object

What does Newton's third law state about two colliding objects?

• Both objects stop moving

• The lighter object moves faster

• Speed is always conserved

• For every action, there is an equal and opposite reaction.

In a collision, how does the force exerted by the first object on the second object compare to the force exerted by the second object on the first?

• They do not affect each other

• The forces are equal in magnitude, but opposite in direction

• The forces point in the same direction

• One is stronger than the other

Which of the following situations can NOT be explained using Newton's third law?

• A soccer ball being kicked and moving

• Two cars experiencing a head-on collision

• A book on a table not falling due to gravity

• The thrust of a rocket propelling it upwards

If two objects of different masses collide, which of the following is true?

• The lighter object experiences a greater force

• The force depends on the object's speed

• The two objects experience the same force

• The heavier object experiences a greater force

How does the mass of an object affect its motion?

• Heavier objects need more force to change motion

• Heavier objects move faster

• Mass has no effect on motion

• Lighter objects need more force to change motion

What factors determine the change in an object's motion?

• Its mass and speed

• Sum of forces on it and its mass

• Its size and mass

• Its color and shape

What is the result of unbalanced forces acting on an object?

• The object's motion changes

• The object's color changes

• The object becomes imbalanced

• The object's mass increases

If more force is applied to a stationary object, what is likely to happen?

• The object would shrink

• The object would get heavier

• The object would move faster

• The object would change shape

What is the relationship between the net force on an object and its motion?

• All forces stop an object's motion

• The object moves in the opposite direction of the force

• The object's motion does not depend on the force

• The object’s change in motion depends on the net force
