Energy can be stored in an elastic material when it is stretched.
Identify that the energy of a moving object depends upon its speed. Give examples of how an object’s energy of motion increases when the object’s speed increases.
Describe how energy can be stored in an elastic object or material by stretching it. Use diagrams to describe ways that the energy stored in a stretched object can be used to make objects move.
The energy obtained from electrical outlets is electrical energy that was produced at an electrical power plant. Electrical energy can be generated and then transmitted over great distances. Batteries are portable sources of electrical energy.
Ask questions and predict outcomes about the changes in energy that occur when objects collide.
Identify, as basic forms of energy; light, heat, sound, electrical, and energy of motion.
Observe that electricity can be transformed into heat, light, and sound as well as the energy of motion. Explain that electrical circuits provide a means of transferring electrical energy from sources such as batteries to devices where it is transformed into heat, light, sound, and the energy of motion.
