Kinetic and Potential Energy Stores
Movement means energy in a object's kinetic energy store
Anything that's moving has energy in its kinetic energy store
Energy is transferred to the kinetic store when an object speeds up and is transferred away when it slows down
Energy in the kinetic store depends on the object's mass and speed
The greater the mass and the faster it is, the more energy there will be
E(k) = 1/2MV^2
Kinetic energy (j) = 1/2 * Mass (kg) * Speed (m/s) ^2
Raised objects store energy in gravitational potential energy stores
Lifting objects in a gravitational field requires work
Causes a transfer of energy to the gravitational potential store of the raised object
The higher the object is lifted, the more energy is transferred to the store
The amount of energy in a G.P.E store depends on the object's mass, height and the strength of the gravitational field the object is in
E(p) = MGH
G.P.E (j) = Mass (kg) * Gravitational field strength (N/kg) * Height (m)
Falling objects also transfer energy
When something falls. energy from its gravitational potential store is transferred to its kinetic store
For a falling object when there's no air resistance:
Energy lost from the G.P.E store = Energy gained in the kinetic store
In real life, air resistance acts against all falling objects
Causes some energy to be transferred to other energy stores
E.G, the thermal stores of the object and surroundings
Stretching can transfer energy to elastic potential energy stores
Stretching or squashing objects can transfer energy to its elastic potential store
So as long as the limit of proportionality has not been exceeded, energy in the elastic potential store can be found using:
E(e) = 1/2KE^2
Elastic potential energy (j) = 1/2 * Spring constant (N/m) * Extension (m)
