What are two ways to calculate gravitational potential energy?
Gravitational potential energy changes into kinetic energy. 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.
How do you calculate gravitational potential?
Gravitational Potential
- The equation for potential is:
- G = the universal gravitational constant.
- m = the mass causing the field.
- r = the distance between the centre of the mass causing the field and the point you are considering.
- Just like potential energy, the biggest value of potential you can get is zero.
How do you calculate GPE loss?
The net work on the roller coaster is then done by gravity alone. The loss of gravitational potential energy from moving downward through a distance h equals the gain in kinetic energy. This can be written in equation form as −ΔPEg = ΔKE.
