1. Work and Energy
Notes on Chapter 5

2. Energy Intro Energy Work Defn: The ability to cause change
Defn: The transfer of energy through motion
Equation: Work = Force x Distance
W = Fd
Units = Joules

3. Kinetic Energy Defn: Energy in Motion Equation: KE = ½mv2
Units = Joules

4. Gravitational Potential Energy
Defn: Energy due to height and weight of an object
Equation: PE = mgh
where g is 9.8m/s2 on Earth
Units = Joules

5. Mechanical Energy Both Kinetic and Potential Energy
Equation: ME = KE + PE
Units = Joules
Law of Conservation of Energy
Defn: Energy can neither be created nor destroyed, it is only transferred.
Hint: think of a swing

6. Some other types of Energy
Potential Energy - stored energy
Chemical Potential Energy - stored in bonds
Thermal Energy - energy due to heat
Electrical Energy - energy due to moving charges
