Just use the formula for potential energy: PE = mgh (mass x gravity x height).
The potential energy (PE) is 110.93 Joules, using 9.8 as the acceleration of gravity.
Gravitational potential energy = mgh = 3 x 9.8 x 8 = 235.2 joules.
At 100 meters this rock's potential energy is 980 joules.
If the movement is due to gravity, that is the material is moving closer to the earth's centre, then the energy change in the movement is a change in gravitational potential energy. All objects are attracted to the earth by gravity, the force they experience is equal to Mass(kg) x Gravitational Constant G =9.81(meters/sec2), the force being in Newtons. Therefore as energy = force x distance, the potential energy of any object raised through a height H meters is M x G x H, and this will be in Joules.
Gravitational potential energy = m*g*h = 75*9.8*3 = 2205 Newtons.
Just use the formula for gravitational potential energy, which is equal to mgh (mass x gravity x height). Close to Earth, gravity is approximately 9.8 newtons/meter.

That depends what kind of "potential energy" you are talking about, but without further specification, this usually refers to gravitational potential energy. The formula for gravitational potential energy is PE = mgh, that is, mass x gravity x height. If mass is in kg. and gravity in meters per second square (use the value 9.82 for Earth's gravity), and height in meters, then the energy will be in Joule.That depends what kind of "potential energy" you are talking about, but without further specification, this usually refers to gravitational potential energy.

U = m g h Where U is Gravitational Potential Energy (measured in Joules) m is Mass (measured in kilograms) g is Gravitational Acceleration (~9.8 meters/second2) h is height (measured in meters)
Gravitational potential energy = mgh = 3 x 9.8 x 8 = 235.2 joules.
Gravitational potential energy = Mass x gravity x heightTherefore, an object at ground level is 0 meters above the ground, thus having no potential energy.PE = mghm = massg = gravitational accelerationh = height
Gravitational Potential Energy.
At 100 meters this rock's potential energy is 980 joules.
Potential Energy The object is not in movement.
After the car is dropped, it has NO gravitational potential energy.Before it's dropped, you can calculate the potential energy as mgh (mass x gravity x height). You can use 9.8 for gravity.
