What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Why is it harder for the boy in Image B to get down the hill?

• Motion
• Friction
• Work
• Displacement

Which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force

What happens when two forces act in the same direction?

• They cancel each other out.
• The stronger one prevails.
• Their strengths are added.
• Their sum divided by the two is the total force.

Any time the forces are unbalanced, an object will remain at rest. True or false?

• true
• false

8 N to the left , and 4 N to the right. Find the net force. Is this balanced 

• 12 N Right  No
• 4 N Left  No
• 12 N Right  Yes
• 4 N Left  Yes

a tendency of an object to resist change in its state of motion

• inertia
• kinetic energy
• potential energy
• force

Any two objects with mass attract each other with a type of force 

• kinetic energy
• potential energy
• inertia
• gravitational force

An object at rest will remain at rest or in the same uniform motion unless acted upon by an unbalanced force: law of inertia.

• Newton's First Law of Motion
• Newton's Second Law of Motion
• Newton's Third Law of Motion

If one object exerts a force on a second object, the second object exerts a force equal in magnitude and opposite in direction on the object body; law of interaction

• Newton's First Law of Motion
• Newton's Second Law of Motion
• Newton's Third Law of Motion
