Question

an object moving in a circular path at constant speed has constant

Answer 1

Maybe Energy remains Constant

Answer 2

Answer:

Option (a) Energy

Explanation:

We know that, uniform circular motion is a non-uniform motion because of variable velocity and so goes for acceleration.

So, putting acceleration and velocity aside, we are left with displacement and energy. Now, there is no point in talking of displacement as it depends upon our will as of how long and where we want it i.e. its variable too.

Now, all we have left is energy. Let us find the reason energy being constant here. We know that;-

    Kinetic Energy, K.E. = 1/2 mv²

Since, Kinetics energy is scalar and its V is its speed and not velocity. Also, mentioned in question that the speed is constant. Therefore, neglecting the mass being constant, energy comes out to be a constant.

Hope it helps! ;-))
