Newton's Law states that a body at rest..
will tend to remain at rest; while a body in motion will tend to remain in motion
Newton's second law of mechanics states that Force =
mass X acceleration
normal force is
the perpendicular force exerted on an object that is resting on some other surface
Newton's third law of mechanics. for every force...
there is an equal and opposite force
what type of surfaces tend to create less friction
flatter and harder
Fd ; F is the magnitude of the force exerted and d is the displacement of the object on which the force is exerted.
