Energy: Conservation and Transfer
7.P.2. Understand forms of energy, energy transfer and transformation and conservation in mechanical systems.
7.P.2.3. Recognize that energy can be transferred from one system to another when two objects push or pull on each other over a distance (work) and electrical circuits require a complete loop through which an electrical current can pass.
7.P.2.4. Explain how simple machines such as inclined planes, pulleys, levers and wheel and axels are used to create mechanical advantage and increase efficiency.
