Gravity. That energy is called gravity. Take it from an unknown person
There is gravitational potential energy (PE) and kinetic energy (KE).
PE = mgh
KE = 1/2 mv2
The sum of these would represent the total mechanical energy of the book.
energy is mass x gravity acceleration x height = .5 x 9.81 x 1.5 = 7.36 joules

Referenced to the floor, 0.5 kg of mass 2 meters above it has(M) (g) (h) = (0.5) (9.8) (2) = 9.8 joulesof gravitational potential energy
Gravitational potential energy = mgh = 3 x 9.8 x 8 = 235.2 joules.
At 100 meters this rock's potential energy is 980 joules.
Use the formula PE = mgh (gravitational potential energy = mass x gravity x height). You can use 9.8 [meters/second2] for gravity. The answer will be in joules.
Just use the formula for gravitational potential energy:GPE = mgh (mass x gravity x height) Gravity is about 9.8 meters/second squared. Since all units are SI, the answer will be in joules.

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.
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.
Use the formula PE = mgh (gravitational potential energy = mass x gravity x height). You can use 9.8 [meters/second2] for gravity. The answer will be in joules.
Gravitational potential energy = m*g*h = 75*9.8*3 = 2205 Newtons.
20 kilograms and 5 meters? Potential energy = mass * gravitational acceleration * height PE = (20 kilograms )(9.80 m/s2)(5 meters) = 980 Joules of potential energy -----------------------------------------
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.
