Energy

What is energy? Energy is defined as the ability to do work.

Types of Energy There are multiple types of energy. We will be talking about five (5) basic types of energy. 1.Potential Energy 2.Kinetic Energy 3.Mechanical Energy 4.Thermal Energy 5.Electrical Energy

Potential Energy Potential energy is the stored energy of position possessed by an object.

Potential Energy

Gravitational Potential Energy is the energy stored in an object as the result of its vertical position or height. Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Kinetic Energy Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. where m = mass of object v = speed of object

Kinetic Energy Example: Determine the kinetic energy of a 625-kg roller coaster car that is moving with a speed of 18.3 m/s. KE = 0.5*m*v2 KE = (0.5) * (625 kg) * (18.3 m/s)2 KE = 1.05 x105 Joules

Kinetic Energy Example: Missy Diwater, the former platform diver for the Ringling Brother's Circus, had a kinetic energy of J just prior to hitting the bucket of water. If Missy's mass is 40 kg, then what is her speed? KE = 0.5*m*v J = (0.5) * (40 kg) * v2 300 J = (0.5) * v2 600 J = v2 v = 24.5 m/s

Mechanical Energy Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
