Describe the relationships among temperature, heat, and thermal energy?

As we experimented in our class, all of them are related to temperature but heat is just warm weather thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated. And temperature is all weather in general.

Idont understand the question

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.
