What is Energy
اسلاید 1: What is Energy?
اسلاید 2: What is Energy?The ability to do work or cause change.
اسلاید 3: What are the different forma of Energy?
اسلاید 4: What are the different forms of Energy?Energy has a number of different forms, all of which measure the ability of an object to do work on or change another object.In other words, there are different ways that an object can possess energy.
اسلاید 5: What are the different forms of Energy?Kinetic EnergyPotential EnergyThermal, or heat energyChemical EnergyElectrical EnergyElectrochemical EnergyElectromagnetic Energy (light)Sound EnergyNuclear EnergyMechanical Energy
اسلاید 6: Define Potential Energy
اسلاید 7: Define Potential EnergyPotential energy is energy due to position or stored energy. Potential energy is also called gravitational potential energy.
اسلاید 8: Give an example of potential energy
اسلاید 9: Give an example of potential energyBy stretching a rubber band, you give it potential energy. A vase on a shelf has stored potential energy. A football being held by a quarterback has potential energy until it is thrown and it turns into kinetic energy.
اسلاید 10: Define Kinetic Energy
اسلاید 11: Define Kinetic EnergyKinetic energy is the energy of motion. Kinetic energy is measured by how much is work done to put an object in motion or to rest.
اسلاید 12: Give an example of kinetic energy
اسلاید 13: Give an example of kinetic energyA basketball player has kinetic energy. The movements that she does show the energy that is being displayed while she is moving. When you are running, walking, or jumping, your body is exhibiting kinetic energy.
اسلاید 14: Give an example of something that has both potential and kinetic energy.
اسلاید 15: Give an example of something that has both potential and kinetic energy.A waterfall has both kinetic and potential energy. The water at the top of the waterfall has stored potential energy. Once the water leaves the top of the waterfall, the potential energy is changed into kinetic energy.

اسلاید 17: Describe Conservation of Energy
اسلاید 18: Describe Conservation of EnergyEnergy cannot be created or destroyed; it can only be changed from one of form of energy to another form. The amount of energy stays the same.
