You are riding on a rollercoaster and the ride is nearing its end. As the ride car pulls into the start/finish area, the cruel conductor suddenly engages the brakes. What will your body do and WHY?

• Move forward because you are at rest and want to remain at rest

• Move forward because you are in motion and want to stay in motion

• Move backward because you are in motion and want to stay in motion

• Move backward because you are at rest and want to remain at rest

You are at an amusement park at the top of a drop tower. You hear a couple of clicks and then you plummet (accelerate) towards the ground and your body suddenly moves off the seat when you start to descend. Why does this occur?

• Magic.

• Gravity causes your body to move upward.

• You are in motion and want to stay in motion.

• Your are at rest and wish to remain at rest.

Objects require an unbalanced force to change their motion or to move from rest; otherwise, they will continue to be in motion or at rest. This statement is essentially

• Newton's 1st Law.

• Newton's 2nd Law.

• Law of Universal Gravitation.

• U.S. Law.

An object will not move or change its motion if the forces acting on it are

• balanced.

• unbalanced.

• negative.

• in opposite directions.
