Energy Transformations Quiz

What is thermal energy?

• The energy stored in the nucleus of an atom

• The energy generated by the Earth's magnetic field

• The energy produced by the movement of tectonic plates

• Internal energy of an object due to the kinetic energy of its atoms and/or molecules

Give an example of an object with high kinetic energy.

• A stationary rock

• A speeding car

• A parked bicycle

• A sleeping cat

Explain the concept of potential energy.

• Potential energy is the energy that an object has due to its temperature.

• Potential energy is the energy that an object has due to its motion.

• Potential energy is the energy that an object has due to its position or state.

• Potential energy is the energy that an object has due to its color.

How is energy defined in the context of physics?

• Ability to do work or produce heat

• The movement of electrons in a circuit

• The color of an object

• The speed of an object

What happens to the thermal energy of a substance when it is heated?

• It turns into light energy

• It increases

• It stays the same

• It decreases

Describe the transformation of potential energy into kinetic energy.

• Potential energy is transformed into sound energy as an object gains speed and motion.

• Potential energy is transformed into light energy as an object gains speed and motion.

• Potential energy is transformed into thermal energy as an object gains speed and motion.

• Potential energy is transformed into kinetic energy as an object gains speed and motion.

What are the different forms of energy?

• Red, blue, green, yellow

• Solid, liquid, gas, plasma

• Mechanical, thermal, chemical, electrical, electromagnetic, nuclear, and potential energy

• Speed, distance, time, force

Explain the concept of kinetic energy.

• The energy an object possesses due to its motion.

• The energy an object possesses due to its shape

• The energy an object possesses due to its temperature

• The energy an object possesses due to its rest

Give an example of a transformation of energy from one form to another.

• Electrical energy to thermal energy

• Nuclear energy to light energy

• Potential energy to sound energy

• Chemical energy to kinetic energy

How is energy transferred from one object to another?

• Through processes such as conduction, convection, and radiation.

• Through the process of evaporation

• By using magnets to attract energy

• Through photosynthesis and respiration
