ENERGY
What is Energy
Energy is the ability to cause change.Change in ANYTHING
There are two general types of energyKinetic energyPotential 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 hillCondition- stretching a rubber bandChemical- 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 EnergyKinetic 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 anotherOften times its changes into multiple formsEx. Fireworks, food
Law of Conservation of Energy
Just like mass, energy cannot be created or destroyed
