What unit is Energy measured in?

• NEw

• meters per second

• Joules

• meters per second per second

• 1718.75 kg

• 68,750 kg

• 8593.75 kg

• 1,492. 34 kg

• 400 m

• 2040.82 m

• 4.82 m

• 40.82 m

What unit is used to measure height?

• joules

• meters

• kilograms

• Newtons

What is the relationship between kinetic energy and velocity?

• There is no relationship

• If velocity changes, then kinetic energy goes up A LOT.

• Velocity doesn't affect kinetic energy.

• If velocity goes up, kinetic energy drops.

What is the difference between kinetic energy and potential energy.

• Potential energy can only be detected in very small objects, but kinetic energy is in all objects

• Kinetic energy is only present on Earth.

• Kinetic energy is moving energy and potential energy is stored energy.

• Potential energy can be destroyed, but kinetic energy cannot.
