What is potential energy ?
Potential energy is stored energy.
This energy depends on position (위치).
This energy depends on condition (상태).
Give 4 examples of potential energy.
Chemical energy
Nuclear energy
Elastic energy
Gravitational energy

What is kinetic energy ?
Kinetic energy is motion (움직임) energy.
Movement creates energy
Faster objects have more kinetic energy.
Heavier objects have more kinetic energy.
Give 5 examples of kinetic energy.
Mechanical energy
Thermal energy
Sound energy
Electrical energy
Light energy

What is the formula used to calculate potential energy ?
Ep = mgh
Ep = Energy in Joules (J)
m = mass in kg
g = gravity in m/s2
h = height in meters (m)
Gravity is always 9.8 m/s2
What is the formula used to calculate kinetic energy ?
Ek = ½ mv2
Ek = Energy in Joules (J)
m = mass in kg
v = velocity in m/s
