Change in velocity divided by time is acceleration, but velocity divided by time has no particular significance.
velocity divided by the time interval
At a small time interval, the average velocity is approximately equal to the instantaneous velocity. However, the values of the average velocity and the instantaneous velocity approach each other , as the length of the time interval is decreased more and more.
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.
A body has uniform velocity if it covers equal displacement in equal intervals of time however short the interval may be.
No, It is the average velocity.
A change in velocity over a time interval is called an acceleration if the velocity is increasing, or a decelleration if the velocity is decreasing.
Divided by time.Average acceleration is (change in velocity) / (time interval) Instantaneous acceleration is calculated by making the time interval very small. This is written as dv/dt.
a=dv/dt average velocity = displacement divided by time take. so average velocity = displacement/time taken.
when a body travels unequal displacement in equal interval of time or visa-versa, it is said to have non-uniform velocity
