Newton’s First Law of Motion Inertia A body in motion tends to stay in motion unless acted upon by an outside force. A body at rest tends to stay at rest unless acted upon by an outside force. A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force.
Newton’s Second Law F=ma The amount of force, F, is directly proportional to the product of the object’s mass, m, and its acceleration, a. Force is measured in Newtons 1 Newton = 1 (kg*m)/s 2 The net external force on a body will cause it to accelerate in the direction in which the force is acting.
Newton’s Third Law The law of interaction. For every action, there is an equal and opposite reaction. Whenever one body exerts a force on second body, the second body must exert a force on the first body that is equal in magnitude but opposite in direction.
Newton’s 3 Laws of Motion Review 1 st Law – Inertia 2 nd Law – F = ma 3 rd Law – For every action, there is an equal and opposite reaction.
