Consider the following statements:
(a) Change in momentum is impulse.
(b) A body is momentarily at rest when it reverse the direction.
(c) For stable equilibrium force has to be zero and potential energy should be minimum.
(d) Force required to accelerate a mass in two perpendicular directions is never same.
Which of the above statements are correct?

A
All of the above
💡 Explanation:
All of the above
Impulse = Force$\times$time = $m\Delta{v}$ = Momentum
A body will be at rest for a moment when it changes direction.
When a body is in equilibrium it always has minimum potential energy and no force is acting upon it.
Force is a vector quantity and hence its direction will result in different force quantity.
