Transfer of Energy Mind Map
← Transfer of EnergyHow a force moves energy (work), the kinds of stored potential energy, and how generators and motors change energy from one form to another.
- workEnergy transferred when a force moves an object some distance.You do work when you lift a box onto a shelf.
- forceA push or a pull.She used a strong force to push the heavy box.
- distanceThe length of a path traveled between places.The box moved a distance of two meters.
- energy transferEnergy moving from one object or place to another.Energy transfer happens when the bat hits the ball.
- mechanical energyThe energy an object has from its motion and position.A swinging hammer has mechanical energy.
- kinetic energyThe energy of motion. Faster or heavier objects have more.A rolling bowling ball has a lot of kinetic energy.
- gravitational potential energyEnergy associated with the relative positions of masses; near Earth, raising an object above a chosen reference level increases it.A ball on a high shelf has more gravitational potential energy than one on the floor.
- reference pointA chosen place or object used to describe position, motion, or height.We used the floor as the reference point for height.
- elastic potential energyEnergy associated with stretching or compressing an object, such as a spring.The pulled-back slingshot stores elastic potential energy.
- chemical potential energyEnergy associated with the arrangement of atoms and electrons, which can change during a chemical reaction.A battery holds chemical potential energy.
- electrical potential energyEnergy stored because of where electric charges are compared to each other.Charges pulled apart have electrical potential energy.
- electrical energyEnergy carried by moving electric charges.Batteries supply electrical energy to the flashlight.
- thermal energyEnergy associated with the random motion and interactions of particles in matter; it depends on the amount, type, and state of the material as well as its temperature.A chemical reaction often gives off thermal energy.
- generatorA machine that converts mechanical energy into electrical energy, commonly by moving magnets and coils relative to one another.Turning the crank on the generator lit the bulb.
- electric motorA machine that turns electrical energy into motion.An electric motor spins the fan blades.
