Force and Energy
Definitions of Energy (4-PS3-1 & 4-PS3-3) • Energy can be moved from place to place by moving objects or through sound, light, or electric currents. Objects have more energy when they are moving faster. Conservation of Energy and Energy Transfer (4-PS3-3) • 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. Energy can be transferred in various ways & between objects. PS3.C: Relationship Between Energy and Forces (4-PS3-3) • When objects collide, the contact forces transfer energy so as to change the object's’ motions/ direction · Crash Course!
