Question

defination of acceleration​

Answer 1

Answer:

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.

Explanation:

please mark my Brainliest

Instantaneous acceleration is defined as "acceleration at a y given point or at any instant of time . " if at Δt time interval velocity if ΔV then according to above defination ; to calculate instantaneous acceleration Δt→0 hence, Instantaneous Acceleration a=limΔt→0ΔtΔv=dtdv.
