Energy and Energy Transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What type of energy is released when atoms split or join together?

Back

Atomic (nuclear) energy is the energy that is stored and released when atoms split or join together.

Front

What is the energy transformation in a pencil sharpener?

Back

The energy transformation in a pencil sharpener is Electrical → Mechanical → Sound.

Front

What is the energy chain from the sun to grass to cow?

Back

The correct energy chain is light and thermal → chemical → chemical.

Front

What types of energy does a television transform electrical energy into?

Back

A television transforms electrical energy into light, thermal, and sound energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.
