Energy
Energy is the ability to do work or cause change.
When a living thing does work on another object, some of that energy is transferred. Examples?
Kinetic Energy 1
Kinetic energy is the energy an object has due to its motion; this depends on both mass and speed.
More mass means more kinetic energy
More speed means more kinetic energy
Examples?
Kinetic Energy 2
Calculating Kinetic Energy:
Kinetic Energy = 1/2 x Mass x Speed2
Note- changing the speed has a greater impact on the object’s kinetic energy than changing the mass.
Potential Energy 1
Potential Energy is stored energy that results from an objects position or shape. This object has the potential to do work. When the object was placed where it is or
shaped a certain way, energy was transferred to it. Examples?
Potential Energy 2
Gravitational Potential Energy is an objects potential energy based on gravity. This is dependant on its height relative to a reference point and it’s weight.
Elastic Potential energy is the potential energy of an object that can be stretched or compressed
Law of Conservation of Energy
According to the law of conservation of energy, energy cannot be created or destroyed. (sound familiar? What is another law that is
similar to this?)
