Energy
General Energy
Energy Types
Thermal
Energy associated with the kinetic energy of particles AKA Heat
Latent Heat
Energy needed to change state
The energy needed to change the state of 1g
Latent Heat of Fustion
Energy for 1g to change solid to liquid
Latent heat of Vapourisation
Energy for 1g to change liquid to solid
Q= m L
Specific Heat Capacity
Energy changes within a state
The energy required to heat 1g of a substance 1C
Change in heat = m c T
Temperature
Heat Transfer
Energy being moved from object to object
Convection
Heat Transfer through fluids due to MOVEMENT (Density changes)
Radiation
Heat Transfer via InfraRed waves (VIBES)
Conduction
Heat transfer through solids due to touching particles - CONTACT!
Mechanical Energy
Elastic
The energy in an object due to it being stretched or squashed
Kinetic Energy
The energy associated with movement
Ek = 1/2 mv^2
Elastic Energy
Gravitational Potentail
The energy in an object due to the interaction with gravity
Ep=mgh
Chemical Potential
Electrical
Energy of electrons carrying a charge
The flow of electrons, Measured in Amps. - Measured in Series
Circuits
Types of Ciruit
Series Circuit
One continuous path for the current
Parallel Circuits
More than one path for the
Features of a Circuit
Voltage
The force of the electrons. Measured in Volts. Measured in Parallel
Current
Flow of electricity in a circuit
Resistance
The impedance of current in a component
General Energy Concepts
Power
Work per second
Measured in Watts (W) AKA Joule per second
How much of the energy input is useful
Energy Efficiency = Useful Energy / Total Input x 100 = %
Work
Measured in Joules (J)
Work the amoud of energy needed to complete a task
