Calculating Energy
Kinetic Energy
Kinetic Energy = 1/2 x Mass x Speed^2
Elastic Potential
Elastic Potential = 1/2 x spring constant x extension^2
Gravitational Potential Energy
Gravitational Potential Energy = mass x gravitational field strength x hight
Specific Heat Capacity
energy = mass × specific heat capacity × temperature change
The energy required to raise the temperature of 1kg of a substance by 1°C or 1K.
Energy Stores
A system is an object or group of objects
When a system changes, the way energy is stored also changes
Examples
Ball rolling and hitting a wall
System is a moving ball
When it hits the wall, some of the kinetic energy is transferred into sound
Vehicle slowing down
System is the moving vehicle
When it slows down, kinetic transfers to thermal due to friction between wheels and brakes
