Kinetic and Potenital

energy in motion

energy is being transferred

dependent on mass and velocity of an object ( velocity is speed in a given direction)

the more work that is done, the more energy it has.

EX. it taks more energy to roll a bowling ball at the same velocity(speed) than a golf ball because the bowling ball has more mass, therefore more energy

Kinetic energy increases as mass increases

Kinetic energy increases as velocity increases

Formula to calculate Kinetic Enery

Energy that is stored and held in readiness

ex lifting a book, pull a bow back

Elastic potential Energy- associated with objects that can be stretched or compressed

Gravitational Potential Energy (GPE) associated with height of an object

If you know the weight of an object : GPE= Weight X height

If you know the mass of an object: GPE= Mass X Gravitational acceleration (9.8 m/s² ) x Height

The unit is in Joules (J)
