Question

What is the definition for velocity of projection ?

Answer 1

Velocity is a vector expression of thedisplacement that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (also known as speed ) is the meter per second(m/s). Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude. The direction of a velocity vector can be expressed in various ways, depending on the number of dimensions involved.

Answer 2

velocity is a measure of how fast something moves in a particular direction. in other words, a velocity is a speed with a direction. for instance, if an object move east at 9 meters per second (9m/s), we would say that it's velocity is 9m/ s to the east
