- 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
