TEST REVIEW Energy Transformations

What is the ENERGY OF MOTION? Depending on how it’s described, it can be potential or kinetic.

• mechanical

• radiant

• thermal

• electrical

• sound

What kinetic energy is the MOVEMENT OF ELECTRONS? Applying a force can make some of the electrons move.

• mechanical

• radiant

• thermal

• electrical

• sound

What kinetic energy travels in ELECTROMAGNETIC WAVES through EMPTY WAVES? It includes visible light, x-rays, and radio waves.

• mechanical

• radiant

• thermal

• electrical

• sound

What kinetic energy is the internal energy in substances? It is the vibration and MOVEMENT OF ATOMS and molecules WITHIN A SUBSTANCE.

• mechanical

• radiant

• thermal

• electrical

• sound

What is the movement of energy through substances in waves? It is produced when a force causes an object to vibrate. Energy is transferred through the object in a wave.

• mechanical

• radiant

• thermal

• electrical

• sound

What potential energy is in an object due to its position? It stored in objects by tension (stretch or compression). It’s also called ELASTIC ENERGY.

• mechanical

• gravitational

• chemical

• nuclear

What potential energy is of position or place? It is energy only stored in an object’s height, position, or place.

• mechanical

• gravitational

• chemical

• nuclear

What potential energy is stored in the chemical bonds and is released during a chemical change? BATTERIES, BIOMASS, PETROLEUM, NATURAL GAS, COAL and FOOD are examples.

• mechanical

• gravitational

• chemical

• nuclear

What potential energy is the energy stored in the nucleus of an atom?

• mechanical

• gravitational

• chemical

• nuclear

What energy transformation occurs in a washing machine?

• electrical energy to radiant (light),  thermal (heat), sound, and mechanical energy

• mechanical energy to thermal (heat), chemical, and electrical energy

• electrical energy to thermal (heat) and radiant (light) energy

• mechanical energy to thermal and nuclear energy
