An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

"Relative tangential motion" is a fancy way to say "slipping" or "sliding". Its direction is opposite the relative velocity (or intended velocity).

Its SI unit is m/s² . ... The acceleration due to gravity at the surface of Earth is represented as g. It has a standard value defined as 9.80665 m/s².

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth).http://www.dictionary.com/

For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.

It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.

An object that is at rest will stay at rest unless a force acts upon it. An object that is in motion will not change its velocity unless a force acts upon it.
