Can the equation of kinematics be used when the acceleration varies with time? If not, what form would these equations take?

Text Solution

Verified by Experts

The equations of motion ar 1) v=4+at 2) `s=ut+1/2at^2` and 3) `v^2-u^2=2as`. All these three equations applicable body moves with uniform acceleration `a`.
No, the equations of are not applicable when the acceleration varies with time.
