Unit 8

In class today we learned all about energy, Kinetic energy, Potential energy, Spring potential energy, and Total energy. I posted a picture of coffee because it has nutrients that our body uses for energy. Our bodies need energy from the nutrients in this coffee in order to function well in the morning.

Law of Conservation of Energy - Energy cannot be created or destroyed, it only changes forms. Energy is scaler meaning it only has magnitude not direction.

Kinetic energy would be an object in motion, this energy in a moving object is called Kinetic energy or KE. There is also Potential energy, this energy is in objects that are stationary it is written in an equation as PE. There is a final energy which is called Total energy this is the total amount of energy an object can have. This total energy will always stay the same no matter what happens to the object.

A good example of Kinetic energy would be a ball rolling down a hill or just rolling in general. Kinetic energy is just the energy in a moving object. An example of Potential energy would be the coffee can above. It is completely stationary and thus it has the energy to potentially do something so it's called potential energy. Once a stationary object begins to move the potential energy slowly changes from Potential energy to Kinetic energy.
