Gravitational potential energy, Ug, can be found using the equation Ug = mgy where m is the mass of the object measured in kg, y is the object's height in m, and g is the gravitational acceleration.
We are given that m = 82 kg and y = 2.0 m. "g" is almost always assumed to equal 9.8 m/s2.
Thus, Ug = (82 kg) x (2.0 m) x (9.8 m/s2) = 1607.2 J or 1.6 x 103 if you are using significant figures.
Note that 1 J = 1 kg m2/s2

E= 70 x 9.81 x 2
E= 1373.4 J

∙ 13y agoUsing the formula PE = MGH, that is, potential energy = mass x gravity x height.
2*2*9.8= 39.2 joules
remember the height here is in meters and weight in kg.

If you have a 2kg pendulum bob that is 6 meters above the ground at its high point and 1 meter at its low point how can you figure the kinetic energy?
Calculate the potential energy at its highest point. Don't use the 6 meters above the ground - use the 5 meter difference from the lowest point. This part of the potential energy gets converted into kinetic energy, when the pendulum is at its lowest point. Just assume that all the potential energy (for the 5 meters difference) get converted into kinetic energy.Calculate the potential energy at its highest point.

If a 20-kg weight is 5 m above the ground and then falls toward the ground how much kinetic energy does the weight have when it is 2 m above the ground?
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.
