What happens to the gravitational potential energy of a system if the height of an object is doubled?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
What happens to gravitational potential energy if two bodies of equal masses are brought closer?
Gravitational potential energy at large distances is directly proportional to the masses and inversely proportional to the distance between them. The gravitational potential energy increases as r increases.
How to calculate gravitational potential energy?
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
How does mass and height affect potential energy?
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
What are two ways to calculate gravitational potential energy?
Lesson Summary The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
What factors affect potential energy?
Gravitational Potential Energy is determined by three factors: mass, gravity, and height. All three factors are directly proportional to energy.
Which equation correctly represents the gravitational potential energy of a system?
Gravitational potential energy changes into kinetic energy. The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
What is the energy of position that depends on mass and height which is also called a stored energy?
Potential energy
Potential energy is called the energy of position. Energy that is dependant on height is called gravitational potential energy. Weight (mass x gravity) determines the amount of potential energy.
