What is Energy Energy is the ability to cause change. Change in ANYTHING There are two general types of energy Kinetic energy Potential energy
Kinetic Energy Kinetic Energy is energy of an object due to motion The amount of kinetic energy an object has depends on its mass and speed As mass and speed increase so does kinetic energy
Potential Energy Potential Energy is the energy that an object has due to its position, condition, or chemical composition. Gravitational potential energy- a ball on a hill Condition- stretching a rubber band Chemical- depends on the chemical bonds ○ As bonds break and new bonds form between atoms, energy can be absorbed or released
An object can have kinetic and potential energy at the same time. When a punter punts the ball it is flying through the air with kinetic energy. As it goes up and down there is a change in gravitational potential energy.
Shape Shifting Energy Energy takes many different forms Mechanical Energy The sum of an objects kinetic and potential energy. Sound Energy Kinetic energy caused by the vibration of particles in a medium Electromagnetic Energy Energy transmitted through space in the form of electromagnetic waves Visible light, x-rays, microwaves
Shape Shifting Energy Electrical Energy Energy that results from the position or motion of charged particles Chemical Energy Potential energy due to the arrangement of atoms in a molecule Thermal Energy Kinetic energy of particles The faster particles move and the more particles there are, the higher the thermal energy Heat is transferred from an object at a higher temperature to an object at a lower temperature Nuclear Energy Energy that comes from the breaking apart of a nucleus of an atom
Transformers Energy can change from one form to another Often times its changes into multiple forms Ex. Fireworks, food
Law of Conservation of Energy Just like mass, energy cannot be created or destroyed
