Potential Energy• Potential energy (PE) =
stored energy of position possessed by an object
Examples:• The ball of a demolition
machine• A stretched bow• Coconuts in a tree• There are 2 types of
potential energy:
1. Gravitational Potential Energy• Gravitational potential energy =
(PEgrav) the energy stored in an object as the result of its vertical position or height.
• The energy is stored as the result of the gravitational attraction of the Earth for the object.
• Example: The PEgrav of the massive ball of a demolition machine is dependent on two variables - the mass of the ball and the height to which it is raised.
Kinetic Energy• Kinetic Energy = (KE) energy of motion• There are many types of kinetic energy, but
we are going to focus on only one type: energy due to motion from one location to another.
• Examples:– Roller coasters going downhill– Skateboarding up and down a half-pipe– Wind
Calculating GPE• GPE = mgh• m = mass of object (kg)• g = acceleration due to gravity
– on Earth it equals 9.8 m/s2
• Δ h = change in height of object (meters)• PEgrav units are Joules(J) because we are measuring
energy.• Recall the weight (w) is mass x gravity (w = mg). As a
result, PEgrav can also be calculated if you are given weight.– PEgrav = wΔh
Calculating KE
• KE = ½ m v2
• ½ = 0.5 or half (constant with no units)• m = mass of object (kg)• v2 = velocity2 or velocity x velocity (m/s)• KE units are Joules because we are measuring
energy.
