Types of Energy

Front

Energy that is stored in the nucleus of an atom is called _________ energy.

Back

Nuclear energy is the energy stored in the nucleus of an atom, released during nuclear reactions.

Front

What kind of energy is represented in the picture? (Chemical, Thermal, Sound, Nuclear)

Back

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

Front

What two factors affect an object's kinetic energy? (mass and speed, area and volume, weight and height, weight and speed)

Back

Kinetic energy is affected by mass and speed; the formula is KE = 1/2 mv².

Front

Which is the best example of kinetic energy? (a car parked on a steep hill, a tennis ball rolling across the court, a picture hanging on the wall, a piece of coal before it's burned)

Back

A tennis ball rolling across the court is a clear example of kinetic energy, which is the energy of motion.

Front

What kind of energy is shown here? (electrical, thermal, chemical, nuclear)

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.

Front

Define potential energy.

Back

Potential energy is the stored energy in an object due to its position or state, such as a rock on a hill.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its position in a gravitational field, calculated as PE = mgh.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What type of energy is associated with the motion of particles in a substance?

Back

Thermal energy is associated with the motion of particles in a substance, contributing to its temperature.
