Gravitational potential energy = mgh = 3 x 9.8 x 8 = 235.2 joules.
10 newton-meters with respect to the ground
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
The mass' approximate potential energy at four meters is 784 joules.
Calculate the gravitational potential energy between 5 m and 2 m above the ground. If you ignore air resistance, all of that potential energy will be converted to kinetic energy, so that's the answer.
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

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)
Potential energy = (weight) x (height) = (mass x gravity) x (height) = (742 x 9.8) x (5) = 36,358 joules(with respect to the ground)
Please use the formula PE = mgh. You can use 9.8 for gravity.
Use the formula PE = mgh (potential energy = mass x gravity x height). Use 9.8 meters per second square for gravity. Answer is in Joule.
