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.
