In a solid state, the molecules have the least amount of energy. They just stick close together and vibrate in place. As the molecules gain more energy, they are able to move around more freely. In the liquid state, the molecules have enough energy to sort of tumble over each other.
Mass = that which causes and object to have inertia
Newton’s First Law= a special case of Galileo’s Law of Inertia
Impulse= force multiplied by time
Momentum= velocity multiplied by mass
Velocity= momentum/mass
Newton’s Second Law= the acceleration of a mass directly proportional to the force acting on it
