Energy Efficiency Flashcards
True or False?: Energy cannot be created of destroyed, just changed in form.
True: Energy CANNOT be created of destroyed, just changed in form.
True or False?: Energy transferred into unwanted forms of energy are called “used”.
False: Energy transferred into UNWANTED forms of energy is called “WASTED”.
If gravitational potential energy is lost what is gained?
If gravitational potential energy is lost, KINETIC energy is gained.
Energy that is not seen doing useful work, the energy is wasted. What are the two wasted/ useful energies in a cordless drill?
Wasted energies found in a cordless drill include heat and sound whilst kinetic (movement) energy is being accurately used.
