What does not affect the gravitational potential energy of an object

As we know that gravitational potential energy is

U = mgh

so it is independent of the speed of object. So speed of object will not affect the gravitational potential energy.

Explanation:

As we know that at any height from the ground the potential energy of the mass is given by

so potential energy depends on

1) mass of object(m)

2) acceleration due to gravity(g)

3) height from the earth surface(h)

So here we can say that gravitational potential energy is independent of the speed of object with which it is moving

so here the parameter that will not effect the gravitational potential energy is the speed of object

i think the answer is a and b

i wish you luck
