Why is the gravitational potential energy of two objects negative?
The gravitational potential energy of two objects is negative because it is defined as the work done by gravity when the objects move closer together, which results in a decrease in potential energy.
Can gravitational potential energy be transferred between objects?
Gravitational potential energy can be transferred between objects when one object loses gravitational potential energy while another gains it. This transfer of energy typically occurs as objects move in a gravitational field, such as when an object falls from a height to the ground. The total amount of gravitational potential energy in the system remains constant, but it can be transferred between objects within the system.
Do all objects have potential energy?
No, not all objects have potential energy. Potential energy is the energy an object has due to its position or state, such as gravitational potential energy or elastic potential energy. Objects that are stationary or lack any form of potential energy do not possess it.
What could gravitational potential energy objects be?
Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. Objects like a book on a shelf, a pendulum at its highest point, or a ball held above the ground all have gravitational potential energy. This energy can be converted into kinetic energy when the object is in motion.
What happens to the value of the Gravitational Potential Energy of a system of objects as the value of r increases?
The value of the Gravitational Potential Energy decreases as the distance (r) between the objects increases. This is because the gravitational force weakens with distance, resulting in a decrease in potential energy as the objects move farther apart.
What is the equation for calculating an object's gravitational potential energy?
The equation to calculate an object's gravitation potential energy is: PE=MGH where: PE is gravitational potential energy M is the objects mass G is the acceleration due to the gravitational pull of the Earth on its surface ( 9.8 m/s2) H is the height from the location that would give it zero potentional energy (generally the ground)
What is the difference between gravitational potential and elastic potential energy?
Elastic potential energy is the amount of energy that is stored in a material that can be compressed. One can measure the elastic potential energy in a material by the equation E = 1/2kx^2 k is the spring constant of an object. The spring constant tells you how stretchy (or elastic) a material is. x is the distance that the object is stretched or compressed. Gravitational energy is the potential energy between two masses with a gravitational field. Two masses will always have a gravitational pull towards each other so there is potential energy between two masses. The gravitational energy between two objects can be modeled by the equation E= Gm1m2 / r G is the gravitational constant 6.67x10^-11 m^3/Kg.s^2 m1 and m2 represent the masses of the two objects r is the distance between the two objects. The greater the distance between the two objects, the weaker the gravitational potential energy.
Why is the gravitational potential energy of two objects negative?
The gravitational potential energy of two objects is negative because it is defined as the work done by gravity when the objects move closer together, which results in a decrease in potential energy.
Can an objects mechanical energy be equal to its gravitational potential energy explain?
Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
What is related to an objects height?
Gravitational potential energy

Which mass has more potential energy?
A more massive objects have a greater gravitational potential energy.
The equation for gravitational potential energy is what?
EP = -mGM/r
Can a objects mechanical energy be equal to its gravitational potential energy?
Yes, an object's mechanical energy can be equal to its gravitational potential energy. Mechanical energy is the sum of an object's kinetic and potential energy, and gravitational potential energy is a type of potential energy determined by an object's position in a gravitational field. When the object is at rest or its kinetic energy is zero, its mechanical energy will equal its gravitational potential energy.
