Depending on the reference point you choose, which is arbitrary, there may be non-zero GPE. But what really matters physically is the change in GPE, which in this case is zero. ΔGPE = 0.freshbox said:So GPE=0?
My understanding is that if there is height, there is GPE.
Gravitational Potential Energy is the energy that an object possesses due to its position in a gravitational field. It is directly related to the height of an object and the strength of the gravitational force acting on it.
Yes, there is still Gravitational Potential Energy on a horizontal surface. Even though the object is not at a higher height, it still has the potential to fall and release energy due to the Earth's gravitational pull.
The formula for Gravitational Potential Energy is mgh, where m represents the mass of the object, g is the acceleration due to gravity, and h is the height of the object. On a horizontal surface, the height is usually measured from the surface to the center of mass of the object.
Yes, Gravitational Potential Energy can be negative on a horizontal surface. This occurs when the object is below the reference level and the gravitational force is acting in the opposite direction of the object's movement. In this case, the potential energy is converted into kinetic energy.
Gravitational Potential Energy does not directly affect an object's motion on a horizontal surface. However, if the potential energy is converted into kinetic energy, it can affect the object's speed and direction of motion. The object may also experience friction, which can further affect its motion.
