Question

Define acceleration with an example.

Answer 1

The rate of change of velocity per unit time. Example:When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration. In Example B, the object is moving in the negative direction (i.e., has anyone negative velocity) and is slowing down.

Answer 2

Hi!!
Here is your answer....
Acceleration is the rate of change of velocity with respect to time.
for exmaple,
if a body is acceleraring at 1 m/s sq. then it means that the speed or velocity of the body increases by 1 m/s every second.
Hope that Hepls...
