They define it as the product of how far the object goes multiplied by how much force that takes. (W=DF) It the force isn't lined up with the direction of travel, you have to use the formula W=DFcos(θ), where θ is how many degrees off the force is from the direction of travel.
velocity, I'm pretty sure.
Acceleration, the change of velocity, occurs. DO NOT EVER CALL IT DECELERATION. That term is for the archetypal caudex ( it's latin, look it up)...Hence, acceleration includes both the increase AND decrease in the rate of change in velocity...and there you have it.
A "vector quantity" is any quantity where the direction matters. In the case of a force, the end result is not the same whether you and I pull an object in the same direction; in opposite directions; or perhaps at a right angle. Briefly, the direction of the force is relevant.

reation force
The term Hertz (abbreviated Hz.) is used to describe the frequency with which current changes its' direction of flow in a second. Such as, our system frequency is 60 Hz.
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.

A change in speed or direction is caused by a force and is called acceleration.
G-Force. Scientific term is also Inertia. This is the force of your body moving in one direction but being pulled in another.
Deformation
There is no such term. The regression (or correlation) coefficient changes as the sample size increases - towards its "true" value. There is no measure of association that is independent of sample size.
