Kinetic energy can be calculated from the mass and velocity of the object that is in motion. Use the thermal energy number to calculate the change in water temperature? video is that the potential energy in this situation, the So I should be calculate the potential energy of 1 kg of water falling 53 m. Then that that number and convert it to thermal energy. When a force is applied to potential energy it converts to kinetic energy. After falling the distance H, the kinetic energy equals the potential energy of Mass of the ball times the acceleration due to gravity times the height, H. So, KE = (Mb x V^2)/2 = Mb x g x H. See? The energy from water can be harnessed to be useful in a variety of different ways through water wheels or in hydroelectricity generating facilities. In your scenario, the gravitational potential energy isn't stored in object but it is stored in object-earth system as a whole. Is potential energy always equal to kinetic energy? down here. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. along this hill. Posted on May 28, 2013 at 7:52 pm. Right before the object The generator converts the turbine's mechanical energy into electricity. Because its potential energy is converted into kinetic energy, you can write the problem as the following:

Plugging in the numbers and putting velocity on one side, you get the speed:

The velocity of 7.7 meters/second converts to about 25 feet/second. 1V = 1J / C. Determine the body's speed, v, in m/s. now it's going to be going in the horizontal I will see you in That energy is conserved. When an object falls, its gravitational potential energy is changed to kinetic energy. Kinetic energy is defined as the energy of a moving object. Potential energy of a spring is defined by the equation Us = 1/2kx^2. height is 10 meters. He has authored Dummies titles including Physics For Dummies and Physics Essentials For Dummies.
