Question

define speed,velocity, acceleration​

Answer 1

Velocity is the rate of motion in a specific direction.

speed is distance traveled in specific time

accelaration is rate of change of velocity

Answer 2

speed:- the rate at which someone or something moves or operates or is able to move or operate.

velocity:- The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion. 



acceleration:- In physics, acceleration is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law. The SI unit for acceleration is metre per second squared.
