Science
Gravity
Gravity is the force that pulls down on the universe. Without gravity we would just keep floating forever.
Momentum
Momentum is the combination of the mass and the speed of the object. The formula to find momentum is mass multiplied by its velocity
The 3 Laws of Motion
1st Law of Motion
An object in motion tends to stay in motion, and an object at rest tends to stay at rest unless acted upon.
2nd Law of Motion
The acceleration of an object is dependent upon the force acting on the object and the mass of the object
3rd Law of Motion
Every action has an equal and opposite reaction
