define velocity and acceleration is it possible for an body to have a zero velocity and acceleration justify your answer
Answers
Answer:
Velocity - is defined as the rate of change of displacement as a function of time.
Acceleration - is defined as the rate of change in velocity with respect to time.
Velocity and Acceleration can not be zero.
Explanation:
Lets first look into velocity. Now, velocity can not be zero since it is calculated on distance/displacement. So, where there is distance, there is movement. And, when there is movement, there is acceleration.
However, at some point, velocity can be zero. This is when the change in position from A to B is zero. An example would be : Throwing a ball upwards; the ball will come back at the same position from where it was accelerated upwards.
Answer:
Velocity is the speed of something in a given direction.
Acceleration is the rate of change of velocity per unit of time.
Yes, when the body is just released, u = 0
but g = 10 m/s2
