Which of the following is the tendency for an object to resist a change in motion?

• Inertia

• Friction

• Gravity

• Air resistance

In a car, when you slam on the brakes, the car will stop but your body will keep moving. What law of motion does this demonstrate?

• This demonstrates Newton’s First Law.

• Newton did not have cars in his time so he was not able to observe this kind of motion.

• This demonstrates Newton’s Second Law.

• This demonstrates Newton’s Third Law.

When rockets launch they use thrusters which apply a force against the ground. This force then pushes the rocket up into space. What law does this demonstrate?

• This demonstrates Newton’s First Law.

• Newton did not have rockets in his time so he was not able to observe this kind of motion.

• This demonstrates Newton’s Second Law.

• This demonstrates Newton’s Third Law.
