Question

Define velocity and acceleration
and thanx for your thanx​

Answer 1

Answer:

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 is the rate of change of velocity. ... When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Answer 2

Answer:

Velocity and acceleration both use speed as a starting point in their measurements. Speed, which is the measurement of distance traveled over a period of time, is a scalar quantity. Both velocity and acceleration are vector quantities, meaning that they use both magnitudes and a specified direction.

Here are the basic definitions of velocity and acceleration:

velocity - the rate of displacement of a moving object over time

acceleration - the rate of velocity change over time
