• One

• Two

• Three

• Four

Newton's third law states: For every action there is an ___________ and ____________ reaction.

• extreme and developing

• understandable and measurable

• equal and opposite

• velocity and acceleration

The formula F = m*a is derived from:

• Newton's first law

• Newton's second law

• Newton's third law

• Velocity

A thirty (30) pound weight is hard to lift because:

• Objects with greater mass have more inertia.

• Objects with greater mass have less inertia.

• Objects made of metal are more dense.

• Objects like weights can change gravity.

What causes a ball rolling across the floor to eventually stop?

• The floor doesn't have enough power to stop the ball.

• Friction between the ball and the floor is resisting the ball's forward motion.

• The wind.

• The ball isn't moving fast enough to keep rolling forever.

Which of the following statements is TRUE?

• Unbalanced forces cause acceleration.

• Unbalanced forces do not have a net force that equals zero.

• Unbalanced forces means one force is greater than its opposing force.

• All of the above.

According to Newton's third law, what is happening when you are sitting in a chair?

• The chair is pushing back at you with an equal but opposite force.

• The chair is slowly sinking downwards into the floor.

• The chair is pushing back at you harder than you are pushing on it.

• The chair will accelerate when you get up.

True or False: Mass and weight are the same thing.

• True

• False

Newton's first law states that, unless acted on by an external force:

• An object at rest wants to be in motion, so it will move on its own.

• An object at rest will stay at rest, but objects in motion want to be at rest too.

• An object at rest will stay at rest, and an object in motion will stay in motion

• An object is an illusion: it does not exist.

If you are riding in the car and the driver brakes suddenly, what does your body do?

• Your body stops moving instantly with no effect.

• Your body continues moving forward (especially if you are not wearing a seatbelt).

• Your body gets thrown backwards instantly.

• There is no effect on your body and you can never tell if someone has braked suddenly.
