Topic1: Energy
ENERGY CHANGES IN A SYSTEM
POWER
rate of energy transfer
P = E / T
THERMAL ENERGY
energy due to heat
E = m c 0
GRAVITATIONAL POTENTAIL
energy stored in an object due to its position in a gravitational field
Ep = m g h
KINETIC ENERGY
energy due to motion
Ek 1/2 m v2
Ep = 1/2 k e2
SYSTEM
objects or group of objects
ELASTIC POTENTIAL
Ep = 1/2 k e2
energy stored in a stretched object
SPECIFIC HEAT CAPACITY
the amount of energy required to raise the temperature of 1kg of a substance by 1Celsius
CONSEVATION OF ENERGY
energy cannot be created, destroyed but can only be transferred
WASTED ENERGY
energy can be transferred into a form that is not a desired outcome
EFFICIENCY
useful energy out / total energy in
