How is the gravitational potential energy store of an object increased?
The gravitational potential energy store of an object is increased by raising it to a higher position above the ground or any other reference level, such as lifting it to the top of a hill or building. This increases the distance between the object and the Earth's center of gravity, which results in an increase in its gravitational potential energy. The amount of potential energy gained by an object depends on its mass, the height it is raised, and the strength of the Earth's gravitational field.
The gravitational potential energy of an object is increased by the following steps:
1. Identify the object: Determine the mass of the object for which you want to calculate the gravitational potential energy.
2. Determine the height: Measure the height or altitude from a reference point to the position of the object. This reference point is usually the ground level or a defined height.
3. Calculate the gravitational potential energy: Use the formula for gravitational potential energy, which is given by the equation: Gravitational Potential Energy = mass × acceleration due to gravity × height. The value of acceleration due to gravity is typically approximately 9.8 m/s² on Earth.
4. Multiply the mass, acceleration due to gravity, and height: Multiply the mass of the object by the acceleration due to gravity and the height to obtain the gravitational potential energy.
By increasing the height or altitude of the object, you can increase its gravitational potential energy. It is important to note that the mass of the object and the acceleration due to gravity remain constant in this process.
