how does mass and height affect gravitational potential energy?

The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of GPE the object loses as it falls. ... This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.

All matter has a gravitational field that attracts other objects. The more mass an object has, the greater its gravitational field will be. For example, the Earth has a greater gravitational field than the Moon because it has a much greater mass than the Moon.

The general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space.

Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity. Gravitational potential energy is energy an object possesses because of its position in a gravitational field.

Work = Mass * Gravity * Height The equation above shows how to calculate the work done. As you can see, your work will be the same – no matter which path you take - because your mass doesn't change during the trip. Gravity doesn't change. The final height is the same.

In almost every chemistry and introductory physics textbook you'll find the answer to this is that temperature has absolutely no effect on mass. ... Energy is just a different form of mass, and adding it to a closed system to increase the temperature will increase the mass of the system.

So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

The variation in apparent gravitational acceleration (g) at different locations on Earth is caused by two things (as you implied). ... The distance between the centers of mass of two objects affects the gravitational force between them, so the force of gravity on an object is smaller at the equator compared to the poles.

Two major factors, mass and distance, affect the strength of gravitational force on an object.

Explain gravitational potential energy in terms of work done against gravity. Show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh.

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.

Greater the mass, greater is the gravitational potential energy. The equation for GPE is : GPE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height above the ground. As you can see GPE is directly proportional to mass, and height.

The gravitational potential at a point in a gravitational field is the work done per unit mass that would have to be done by some externally applied force to bring a massive object to that point from some defined position of zero potential, usually infinity . ... The two definitions are equivalent.

Gravitational Potential Energy. Definition: Gravitational Potential Energy ( PEg ) is given by: PEg = mgy, (3) where m is the mass of an object, g is the acceleration due to gravity, and y is the distance the object is above some reference level.

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.

Potential energy is energy that is stored in an object or substance. Gravitational potential energy is energy in an object that is held in a vertical position.

It's like the Earth pulling on you and keeping you on the ground. That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects.
