What is the measurement of heat in an object or substance
Temperature
What is Newton's first law of motion?
For every action there is an equal and opposite reaction.
What happens to the molecules when we add more thermal energy?
The molecules speed up and spread apart.
We have a soccer ball sitting on the field. It stays like that until somebody kicks it. This puts a force on it, causing the ball to move. What law is this?
Newton's 1st Law

Balanced
What is to hit with force while moving
Collision
What is conduction?
When heat moves from one object to another object through direct contact/touch.

What is the rate at which an object’s velocity changes over time.
