What is energy?(pg 107 textbook) Energy is the ability to do work. The metric unit for energy is the joule (J)
Energy (pg 108 textbook) Energy can come in many forms such as thermal or elastic but all forms can be classified into the two categories of kinetic and potential energy. Kinetic energy is the energy of an object in motion for example a toboggan going down a hill has kinetic energy (e.g. electricity, thermal, energy, and sound). Potential energy is stored energy.We can do work because of potential energy found in the food that we eat. A type of potential energy is called gravitational potential energy. This is potential energy that is stored in an object that is able to fall (e.g. an apple held in your hand) Although the two forms of energy are completely different they are both very important.
