Anything with kinetic energy must be

• lifted above the Earth's surface

• in motion

• at rest

• changing direction

• chemical potential

• kinetic

• thermal

• gravitational potential

Plants use photosynthesis to convert Sunlight into __________________________.

This type of energy stays constant and does not change during energy transformations.

• potential energy

• kinetic energy

• mechanical energy

• solar energy

An example of kinetic energy?

• a book sitting on a shelf

• hat and gloves on a table

• cars parked in a parking lot

• a car droving down the street
