Newton’s First Law

Newton’s First Law

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 Second Law

The force (F) acting on a body is equal to the mass (m) of the body multiplied by the acceleration (a) of its centre of mass,

F = ma

Newton’s Third Law

For every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A.
