What is force?

• A push exerted on an object
• A push or pull exerted on an object
• A pull exerted on an object
• Nothing

What is the tendency of an object to resist a change in motion?

• coffee
• motion
• inertia
• gravity

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more mass and requires more force to accelerate.

What type of friction is not moving?

• static
• sliding
• fluid
