What is the equation for elastic potential energy
E = 1/2 K e’2
How is elastic potential energy stored
Energy is stored in a stretched object
What is specific heat capacity
Specific heat capacity is the amount of heat that is needed to increase a temprature of 1kg of a substance by 1 degrees celcius
What is conservation of energy
It is when energy cannot be created or destroyed but only transferred
What is wasted energy
Enrgy transformed into a not desired outcome
Efficiency equation
Useful energy out / totla energy in
What is Power
Rate of energy transfer
What is the equation for power
P = E / t
