Law of Conservation of Energy1. Energy cannot be created or

destroyed. 2. Energy can only be transformed

from one form to another.

Kinetic Energythe energy of motion

Any object, particle or substance that is in motion has kinetic energy.

Can you give some examples?

Kinetic Energy Formula

Kinetic Energy = ½ mass × velocity2

mass – mass of the objectvelocity – velocity of the object

Potential EnergyEnergy stored or held in readiness

**An object in motion can still have potential energy.

Types of Potential EnergyElastic Potential Energy: energy stored in an object that are stretched or compressed

Gravitational Potential Energy: energy that depends on height due to gravity

Chemical Potential Energy: energy that is stored in the chemical bonds of compounds

Potential Energy FormulaGravitational Potential Energy =

mass × gravitational acceleration × height

Gravitational Potential Energy =weight× height

Weight = mass × gravitational acceleration

Gravitational acceleration on Earth is 9.8 m/s2.
