- 1. Multiple Choice
A student kicks a soccer ball into a goal. The speed of the ball is reduced when it hits the net. WHAT CONCLUSION CAN BE DRAWN ABOUT THE KINETIC ENERGY OF THE BALL UPON HITTING THE NET?
The ball's kinetic energy decreases because its speed increases.
The ball's kinetic energy increases because its speed increases.
The ball's kinetic energy increases because its speed decreases.
The ball's kinetic energy decreases because its energy decreases.
- 2. Multiple Choice
The image shows a disc used in disc golf. A disc golfer throws the disc two separate times while playing a round of disc golf.
The disc golfer observes that when thrown at the same angle, the disc drops to the ground more quickly on the SECOND throw. Based on the disc golfer's obseration, which statement is true about the disc on the SECOND THROW?
The disc has more kinetic energy after it lands.
The disc has more kinetic energy when released (or thrown).
The disc has less kinetic energy after it lands.
The disc has less kinetic energy when released (or thrown).
- 3. Multiple Choice
Two cars travel on the same highway as in the picture.
Car P travels at a speed of 65 mph, and car Q travels at a speed of 60 MPH. WHAT CONCLUSION CAN BE DRAWN ABOUT THE KINETIC ENERGY OF THE 2 CARS?
Car Q (60 mph) has LESS energy than Car P (65 mph) because Car Q is moving at a faster speed.
Car P (65 mph) has MORE kinetic energy than Car Q (60 mph) because Car P is mpoving at a faster speed.
Car Q (60 mph) has MORE kinetic energy than Car P (65 mph) because Car Q is moving at a slower speed.
Cars P and Q have the SAME kinetic energy because they are moving at the SAME speed.
- 4. Multiple Choice
TWO OBJECTS (D and T) with the same mass move away from each other at the SAME SPEED. What conclusion can be drawn about the kinetic energy of EACH OBJECT?
Object D has MORE kinetic energy than Object T.
Objects D and T have EQUAL kinetic energy.
Object D has LESS kinetic energy than Oject T.
Objects D and T have NO kinetic energy.
- 5. Multiple Choice

- 7. Multiple Choice
Coach Dean performs jumping jacks in the gym. He starts and stops the exercise for each jumping jack. AT WHICH POINT IS HE USING KINETIC ENERGY and STORING POTENTIAL ENERGY?
Coach Dean stores potential energy when slowing down and uses kinetic energy when speeding up.
Coach Dean uses kinetic energy when slowing down and stores potential energy when speeding up.
Coach Dean uses kinetic energy when stopped and stores potential energy when moving.
Coach Dean stores potential energy when stopped and uses kinetic energy when moving.

Mrs. Stout walks for 3 minutes and then sits down to rest. Then she begins to run for 1 minute. HOW IS HER ENERGY CONVERTED FROM ONE FORM TO ANOTHER?
kinetic energy> potential energy> potential energy
electrical energy> potential energy> electrical energy
potential energy> electrical energy. potential energy
kinetic energy> potentional energy> kinetic energy
- 9. Multiple Choice
A student conducts an experiment with a ball. The student releases the ball, and it drops to the floor and bounces. Imagine this in your mind. WHAT ENERGY TRANSFORMATION TAKE PLACE FROM WHEN THE BALL IS DROPPED TO WHEN IT HITS THE FLOOR?
Potential energy is converted into kinetic energy when the ball is dropped. Then kinetic energy is converted into sound energy when the ball hits the floor.
Kinetic energy is converted into sound energy when the ball is dropped. Then sound energy is converted into kinetic energy when the ball hits the floor.
Sound energy is converted into kinetic energy when the ball is dropped. Then kinetic energy is converted into potential energy when the ball hits the floor.
Kinetic energy is converted into potential energy when the ball is dropped. Then potential energy is converted into sound energy when the ball hits the floor.
- 10. Multiple Choice

The potential energy stored in the marble is converted to heat energy to make the marble move.
The potential energy stored in the marble is converted to electrical energy to make the marble move.
The potential energy in the marble is converted to kinetic energy to make the marble move.
The potential energy stored in the marble is converted to sound energy to make the marble move.
