Energy Transformations

Front

What kind of energy is being shown in the picture?

Back

Potential

Front

As the ball is dropped, the potential energy decreases while the kinetic energy increases however the amount of energy stays the same.

Back

True

Front

The rock has kinetic energy.

Back

False

Front

Which is the best example of kinetic energy?

• A car sitting on top of a hill
• A skateboard on the sidewalk
• A wagon rolling down a hill
• A powerwheel parked in the yard

Back

A wagon rolling down a hill

Front

What is changed to increase the potential energy of an object being dropped?

Back

Height

Front

Which two points have the same potential energy? Options: U & V, S & T, T & X, S & X

Back

S & X

Front

What happens as the ball on the pendulum goes from center to the right in the diagram?

Back

Potential energy increases as kinetic energy decreases

Front

How does energy change?

• The cart has more kinetic energy at the top than when it is going down the hill.
• The cart has potential energy at the top while kinetic energy increases going down.
• The cart has potential energy that is lost going down the hill.
• The cart has kinetic energy at the top of the hill and no potential energy.

Back

The cart has potential energy at the top while kinetic energy increases going down.

Front

How does energy transfer as the ball is bouncing? Options: Kinetic, Potential, Potential, Kinetic; Potential, Potential, Kinetic, Kinetic; Kinetic, Kinetic, Potential, Potential; Potential, Kinetic, Kinetic, Potential

Back

Potential, Kinetic, Kinetic, Potential

Front

Before fruit falls from a tree, how does energy flow? Options: Potential - Kinetic - Sound, Light - Kinetic - Heat, Potential - Sound - Heat, Solar - Kinetic - Heat

Back

Potential - Kinetic - Sound
