4-PS3.DCI. Disciplinary Core Ideas
PS3.B: Conservation of Energy and Energy Transfer
PS3.B:1. Energy is present whenever there are moving objects, sound, light, or heat. When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced. (4-PS3-2), (4-PS3-3)
