Newton's Laws of Motion
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.
