With regard to rotating limbs to project objects, a relationship exists between the <u>velocity</u> of the rotating arm and the<u> </u><u>velocity</u> of the projected object.
In easy words, velocity is the rate at which something moves in a specific route. For instance, the speed of a car touring north on a highway, or the speed a rocket travels after launching.
Speed (v) is a vector quantity that measures displacement (or change in function, Δs) over the exchange in time (Δt), represented by means of the equation v = Δs/Δt. Velocity (or price, r) is a scalar quantity that measures the space traveled (d) over the trade in time (Δt), represented by using the equation r = d/Δt.
The pace is the directional pace of an item in motion as an indication of its price of alternate in function as observed from a selected frame of reference and as measured by way of a particular preferred time.
