Question

Define velocity and acceleration. State their S. I. and C.G.S. unit.​

Answer 1

Answer:

Velocity is a vector quantity that refers to the rate at which an object changes its position. It is a vector expression of the displacement that an object or particle undergoes with respect to time.

The SI unit of velocity is meter/second.

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

si unit -eters per square second

cgs units - (centimeter-gram-second)
