Example of energy in science
WebKinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been … Webenergy transfer, the change of energy from one form to another. According to the first law of thermodynamics, energy can be neither created nor destroyed; in other words, the total energy of the universe remains constant. For example, when a block slides down a slope, the potential energy of the block sitting at the top of the slope is converted to the kinetic …
