Potential Energy Basics. In Motion in Two and Three Dimensions, we analyzed the motion of a projectile, like kicking a football in Figure (PageIndex{1}).For this example, let''s ignore friction and air resistance. As the football rises, the work done by the gravitational force on the football is negative, because the ball''s displacement is positive vertically and the force due to gravity ...

In this explainer, we will learn how to calculate changes in the energy of an object in a gravitational field using the definition of the gravitational potential energy, 𝐸 = 𝑚 𝑔 ℎ. It is an extremely familiar observation that an object released from rest at some point above the surface of Earth will move toward Earth; in other words, it will fall.

This makes sense as a potential energy. The integral F.dr is the work done to move a particle from infinity to a distance r away from the gravitating object. By the work-energy theorem the work done is the change in kinetic energy. We have defined our gravitational potential energy as the negative of this: as a mass moves towards the gravitating object it gains kinetic energy (it …
Description. 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 is the gravitational potential difference between the chosen point and the position of zero potential.
Consider a large spherical body of mass (M) with a coordinate system whose origin coincides with the center of the spherical body (for example, the large body could be the Earth). The force, (vec F(vec r)) on a body of mass (m) (for example, a satellite), located at a position (vec r) is then given by: [begin{aligned} vec F(vec r) = - Gfrac{Mm}{r^2}hat r=- Gfrac{Mm}{r^3}vec ...

Main Idea. Gravitational Potential Energy ([math]displaystyle{ U_{grav} }[/math]) is the energy stored in an object as a result of its position in a gravitational field and attractive forces from surrounding objects.The general case of gravitational potential energy, when two objects with mass are attracted to each other, depends on the distance between the two and …
Gravitational potential energy (GPE) is energy stored in a mass due to its position in a gravitational field. If a mass is lifted up, it will gain GPE (converted from other forms of energy); If a mass falls, it will lose GPE (and be converted to other forms of energy); The equation for gravitational potential energy for energy changes in a uniform gravitational field is:

The equation ΔPE g = mgh applies for any path that has a change in height of h, not just when the mass is lifted straight up.(See Figure 2.) It is much easier to calculate mgh (a simple multiplication) than it is to calculate the work done along a complicated path.The idea of gravitational potential energy has the double advantage that it is very broadly applicable and it …

Local Approximation. The strength of a gravitational field varies with location. However, when the change of distance is small in relation to the distances from the center of the source of the gravitational field, this variation in field strength is negligible and we can assume that the force of gravity on a particular object is constant.
Gravitational Field Strength. The gravitational field strength (g) on the Earth is approximately 9.8 N/kgThe gravitational field strength on the surface of the Moon is less than on the Earth . This means it would be easier to lift a mass on the Moon than on the Earth; The gravitational field strength on the surface of the gas giants (eg.
Gravitational energy or gravitational potential energy is the potential energy a massive object has due to its position in a gravitational field. It is the mechanical work done by the gravitational force to bring the mass from a chosen reference point (often an "infinite distance" from the mass generating the field) to some other point in the field, which is equal to the change in the kinetic energies of th…
