Newton’s Laws of Motion

if all forces acting on a body are balanced, the the object will not change speed or direction

first law

an object at rest has a tendency to remain at rest

first law

an object in motion has a tendency to remain in motion

first law

an object with a given velocity maintains that velocity unless acted on by an external net force

first law

which law is also called the law of inertia

first law

if there is an unbalanced force acting on an object, it will accelerate in the direction of the net force

second law

mass resists acceleration and more mass means more inertia

second law

for every action there is an equal reaction force. the reaction force will have an equal magnitude but in the opposite direction

third law

if object A exerts a force on object B, then B exerts an equal force back upon A in the opposite direction

third law

the extension of a spring is proportional to the force that is applied to it
