kinetic energy and potential energy as the ball moves. The bars in the figure show that the ball's total energy does not change. The Law of Conservation of Energy The total energy in the universe is the sum of all the different forms of energy everywhere. According to the law of conservation of energy, energy can be transformed from one
changes to thermal energy. Thermal energy causes the lamp's bulb to become warm to the touch. Using Thermal Energy All forms of energy can be changed into thermal energy. Recall that thermal energy is the energy due to the motion of particles that make up an object. People often use thermal energy to provide warmth or cook food. An electric space

While the Department of Energy is working hard to develop new technologies to
Energy and Energy Transformations Energy is the capacity to do work. Energy exists in many forms, such as thermal energy and kinetic energy. In an energy transformation, energy changes from one form into another. The transformation can be described using an equation with arrows. 4.2 Work The term work has a specific meaning in physics.
An energy conversion is a change from one form of energy to another. Any form of energy can change into . energy for the guitar 14. light energy 15. In nuclear fusion, nuclei join; in fission, nuclei split apart. . SECTION 2 ENERGY CONVERSIONS 1. 1) potential energy 2) kinetic energy 2. by stretching it 3. Food has chemical energy.
