Energy
- Energy storage
- Thermal/ internal energy
- Kinetic
- KE = 1/2mv^2
- KE = 1/2mv^2
- Gravitational potential
- GPE = M*GFS*H
- GPE = M*GFS*H
- Elastic potential
- Ep = 1/2*spring constant(K)*extention(E)^2
- Ep = 1/2*spring constant(K)*extention(E)^2
- Chemical
- Magnetic
- Electrostatic
- Nuclear
- Thermal/ internal energy
- Transferring energy
- Energy can not bee created
nor destroyed, only transferred
- Energy is transferred by doing work
- Work done = Force * distance
- Work done = Force * distance
- Power is the work done over time
- P= E/T
- P= W.D /T
- Measured in watts
- P= E/T
- Transferring heat
- Conduction
- Convection and
convection currents
- Radiation
- Conduction
- Reducing energy transfers
- Lubricant to reduce friction
- Insulators
- Lubricant to reduce friction
- Energy can not bee created
nor destroyed, only transferred
- Specific heat capacity
- The energy you need to heat 1kg
of a substance by 1 degree C
- Change in energy (Delta E) = M*specific heat
capacity (C)* Change in energy (delta theta)
- Finding specific heat capacity
- Get 1kg of a material with two holes in the top
- Wrap it in insulation
- Measure initial temperature and set the powerpack to 10V
- Measure temperature every minute
- Plot results on a graph the energy
transferred for each degree C
- Use E =PT to find energy as power = 10
- 1/(gradient*mass) = specific heat capacity
- Use E =PT to find energy as power = 10
- Plot results on a graph the energy
transferred for each degree C
- Measure temperature every minute
- Measure initial temperature and set the powerpack to 10V
- Wrap it in insulation
- Get 1kg of a material with two holes in the top
- The energy you need to heat 1kg
of a substance by 1 degree C
- Efficiency = useful
energy out / energy in
- Energy resources
- Non-renewable
- Biofules
- Made from plant waste
- incredibly polluting
- coal
- oil
- gas
- Made from plant waste
- Nuclear
- Biofules
- Renewable
- Wind
- Solar
- Geothermal
- Hydro-electric power
- Wave
- Tidal
