Energy Stores
Gravitational Potensial
GPE = M x G x H
F - GPE = M x G x H
N - 9000 = M x 10 x 15
A - 60
A - Joules
Units
Gravitational Field Strength (EP) = Joules
Mass (m) = Kg
Height (h) = Metres
Kinetic Energy
Ek = 1/2 x M x V2
Units
Kinetic Energy (EK) = Joules
Mass (M) = Kg
Velocity (V) = MPS
Elastic Potensial
Ee = 1/2 x K x e2
Units
Elastic Energy (Ee) = Joules
Constant (K) = N/m
Extension (E) = M
Work
W = F x S
Units
Work (W) = Joules
Force (F) = Neutons
Distance (s) = Metres
Facts
Energy
It can't be created or destroyed
Energy allows everything to happen like movement
Energy is shifted through pathways
GPE
It means when something is lifted it has the potential to fall when energy is transferred from one store to an other
Mass and height affect GPE
Kinetic Energy
the energy is gained by moving
Velocity has a bigger increase on the Kinetic Energy because you square the velocity
Elastic potential
The energy that is gained when something is streched
Work
When you do work you transfer more energy
To increase work you increase the force and distance
Power
it depends upon the work done to the object and the amount of time taken
Power
Power = Energy or work done over time
Units
Power = Watts
Energy = Joules
Time = seconds
