    The Magnitude Of Gravitational Potential Energy Of Three Particles


    Gravitational potential energy (GPE) is a physical property of particles that quantifies their ability to attract other particles. It is one of the four fundamental interactions in the universe. GPE is also the source of the strong force, which holds nuclei together in the nucleus of atoms and determines the properties of elements. In this blog post, we will explore how three particles have great gravitational potential energy and what they mean for our everyday lives.

    Gravitational Potential Energy and the Conservation of Energy

    When three particles are placed in a gravitational field, the gravitational potential energy of each particle is decreased. This decrease in potential energy is due to the fact that the gravitational force between the particles is continually trying to pull them closer together. The total amount of potential energy lost by the three particles is equal to their mass times the gravitational force exerted between them.

    It can be shown mathematically that the total magnitude of this gravitational potential energy is related to the sum of the masses of the particles and to their separation distance. This relationship can be expressed as:

    Gravitational Potential Energy (in joules) = -6.67 x m1 x m2 x G (in Newton/meter)

    where m1 and m2 are the masses of each particle, and G is the gravitational constant (6.67 x 10-11 N/m2). It is important to note that this equation only holds true if both particles are in uniform circular motion around a common center of gravity. If one or more of the particles moves along a path other than a circle, then its associated gravitational potential energy will be different from what’s predicted by this equation.

    Gravitational Potential Energy of Three Particles

    As we’ve seen, mass can be converted into energy when it is moved by a force. This is why objects with more mass have greater gravitational potential energy. The gravitational potential energy of three particles can be calculated using the following equation:

    where m1, m2, and m3 are the masses of the particles, and G is the gravitational constant. In this equation, E represents the total amount of gravitational potential energy. Solving for E yields:

    which gives us a value of 9.8 J/g. This value is significant because it is larger than the 4.8 J/g that is possessed by two particles combined. Additionally, this value exceeds the 6.6 J/g that is found in one particle alone! Why does this matter? Well, because when two or more particles are attracted to each other by gravity, their combined gravitational potential energy is what causes them to move as a unit – and that’s how planets form!


    In this article, we investigated the magnitude of gravitational potential energy of three particles. We found that the maximum gravitational potential energy is greatest for the particle with the largest mass. Additionally, we determined that the total gravitational potential energy is proportional to the product of the masses of the particles. This information can be used to calculate how much weight an object would have if placed in a particular location based on its mass and distance from Earth’s center.
