Skiers at the top of a slope contain gravitational potential energy. In order to calculate gravitational potential energy, one needs to use the formula {eq}U=mgh {/eq}. U stands for gravitational energy, and is typically measured in Joules. M stands for mass and is typically measured in ki...
Elastic potential energy = force x distance of displacement. W = Fs W = elastic potential energy, in Joules F= force, in Newtons s= displacement, m Because the force is = spring constant x displacement, then the Elastic potential energy = spring constant x displacement squared. F = 1/2 ...
Kinetic and potential energy are measured in joules. One joule is equivalent to the amount of energy used when one newton of force is used to move an object one meter of distance. Thermal energy is measured in therms. One therm is equal to 100,000 British thermal units, or 1,055 joules...
Kinetic energy is the energy that a body possesses because of its motion. All forms of energy are measured in joules(J). Gravitational potential energy The other type of mechanical energy is potential energy. Potential energy is the energy that a body possesses because of its position. It can...

The result will be in joules if you used SI units. What is the potential energy of an apple on a tree? For an apple with mass m = 0.1 kg hanging at a height h = 2.5 m, the gravitational potential energy is E = 2.4525 J, or roughly half a calorie. To find this result, multipl...
Perform the multiplication to get the gravitational potential energy in joules (J). Example Suppose a boulder has a mass of 50 kg and sits on a cliff 80 meters high. The gravitational potential energy can be calculated as: E = m x g x h = 50 kg x 9.81 m/s2x 80 m = 39,240 J...
42km/hr ? A 35kg child has 190J of kinetic energy after sledding down a hill. What is the child’s speed in meters per second at the bottom of the hill? Answers ? Calculate the kinetic energy in joules of a 1500kg car moving at the following speeds: ? i. 29m/s KE=1/2mv2=(...
