Newton's first law

A body will remain in it’s state of it or motion at a constant velocity unless a non resultant force acts on it

Normal force

The perpendicular force extended by a surface on an object in contact with the surface

Newton's second law

When a net force acts on an object, the object will accelerate in the direction of the net force with an acceleration that is directly proportional to the force and inversely to the mass of the object

Free fall

Motion of an object underthe influence of gravity only
