What impacts the amount of potential energy?

Velocity (speed) of the object.

Mass and height of the object.

Mass of the object.

Height of the object.

Height of the object and mass.

Explanation:

When u hold a 10kg object at 1km above the surface, it may fall at 309kmph.

When u hold a 20kg object at 2km above the earth the object will fall at 618 kmph.

And so on ...

Mass and height of the object.

Explanation:

The Mass and height of the object impacts the amount of potential energy. Potential energy is the energy possessed by a body by virtue of its position. An object launched in the air possesses potential energy since it covers a particular height (h) between the ground level and the maximum height. The body is also the influence of gravitational force (g)

According to PE formula

PE = mass * acceleration due to gravity * height
