I assume you mean the gravitational potential energy. This is proportional to the mass, so if you change the mass by a factor of "a", the gravitational potential energy will change by the same factor of "a".
it is also halved
When you lift an object, the energy transferred to the object is called gravitational potential energy.
When an object falls down, potential energy is converted to kinetic energy.
Loosing potential energy is stored as kinetic energy.
When an object falls, the potential energy gets converted to kinetic energy.
It becomes kinetic energy. And as an object goes up against gravity, it gains potential energy and loses kinetic energy.
It's potential energy decreases.
An object's potential energy doesn't depend on its speed. You can do anything you like with the object's speed, and it has no effect on potential energy.
It is halved.
It is tranferred/converted into kinetic energy (DECREASES)
It increases.
When you lift an object, the energy transferred to the object is called gravitational potential energy.
When an object is dropped, its potential energy decreases. This is because potential energy is a result of an object's position or height above the ground. As the object falls, it loses height, which leads to a decrease in potential energy. At the same time, the object gains kinetic energy, which is the energy of motion.
When an object falls down, potential energy is converted to kinetic energy.
Loosing potential energy is stored as kinetic energy.
The potential energy will have converted into some other kind of energy. For example, for an object in free fall, it converts to kinetic energy (the object moves faster); if there is some resistance, part of this energy will convert to heat.
When an object falls, the potential energy gets converted to kinetic energy.
It becomes kinetic energy. And as an object goes up against gravity, it gains potential energy and loses kinetic energy.
