Physics
State two factors on which the potential energy of a body at a certain height above the ground depends.
Answer
The two factors on which the potential energy of a body at a certain height above the ground depends are:
- Mass of the body — Greater the mass of the body, greater is the potential energy of the body.
- Its height above the ground — Higher the height of the body above the ground, more is the potential energy.
