FORCES
#1. Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force
Newton's 3 Laws Of Motion:
#2. The second law explains how fast an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time.
For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a:
F = m * a
#3. The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A.
