Newton's Laws of Motion
Newton’s Laws of Motion are foundational principles in physics, explaining how objects behave under various forces. Newton's First Law, also known as the law of inertia, states that an object will remain at rest or in uniform motion unless acted upon by an external force.

Newton's Laws of Motion Newton's Third Law Action reaction forces can cause a change in motion, act on different objects, and cause an equal by opposite reaction Momentum - The result of mass of an object times the object's velocity Action reaction forces are equal in strength but opposite in direction Force may be equal but mass of objects determine the effect of force. For every action, there is an equal and opposite reaction Newton's Second Law As force increases, acceleration increases As mass increases, acceleration decreases Unbalanced forces cause acceleration of an object Force = mass * acceleration (F=ma) Acceleration depends on both force and mass Newton's First Law Object remains at rest or remains at a constant velocity if net force = zero Movement occurs when there is a net force acting on an object Net Force = sum of all forces acting on an object Inertia = tendency of an object to resist a change in motion Object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force.
