What happens to the gravitational energy of an object when it is taken outside the Earth's gravitational field?

• It becomes zero.

  
  

• It increases.

• It decreases.

• It remains the same.

Light energy exists in photons produced when atoms heat up and move faster.

• True

• False

Thermal energy comes from the movement of particles

• True

• False

What are the examples of thermal energy?

• if you throw a ball
