Scientific Law
A rule or principle that describes what happens in nature is a
400
Newton's First Law of Motion
An object moving at constant velocity keeps moving at that velocity unless an unbalanced net force acts on it. What law is this?
400
Newton's Second Law of Motion
This law states that the acceleration of a object is in the same direction as the net force on the object.

Newton's Third Law of Motion
This law states that when one object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and in the opposite direction.

Law of Conservation of Energy
This law states that energy cannot be created or destroyed.
