first law
what is newtons first law?
An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction, unless it is acted upon by an external force
(Law of Inertia)
what is newtons second law
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed as the formula F = ma (Force equals mass times acceleration)
(Law of Acceleration)
what is newtons third law
For every action, there is an equal and opposite reaction
(Law of Action-Reaction)
