The definition of weight.
What is weight is the effect of the force of gravity on mass?
Motion around an axis sometimes known as rotational motion.
What is the angular motion?
Linear velocity is measured by this scalar quantity.
What is speed?

What is the law of acceleration?
Acceleration is proportional to and in the same direction as the unbalanced force applied to it?
F=ma?
