Quiz 33: Final Review 2026

What is Potential Energy (PE)?

• Energy of motion

• Energy created from nothing

• Stored energy based on position

• Energy lost during transfer

Answer explanation

Potential Energy (PE) is defined as stored energy based on position. It is the energy an object possesses due to its location in a gravitational field or other forces, unlike energy of motion or energy created from nothing.

What is Kinetic Energy (KE)?

• Energy of motion

• Stored energy based on position

• Energy that cannot be transferred

• Energy that is destroyed

Answer explanation

Kinetic Energy (KE) is defined as the energy of motion. It is the energy an object possesses due to its movement, making 'Energy of motion' the correct choice. The other options describe different forms of energy.

According to the Law of Conservation of Energy, energy is not created or destroyed, only _________

• measured

• transformed/transferred

• multiplied

• reduced

Answer explanation

According to the Law of Conservation of Energy, energy is not created or destroyed, but rather transformed or transferred from one form to another. This makes 'transformed/transferred' the correct choice.

What is Energy Transfer?

• Energy is destroyed

• Energy moves from one object to another

• Energy is created

• Energy stays in one place

Answer explanation

Energy transfer refers to the process where energy moves from one object to another, such as when heat flows from a hot object to a cold one. This is the correct understanding, as energy cannot be created or destroyed.

Which of the following is NOT a form of energy?

• Light

• Heat

• Gravity

• Sound

Answer explanation

Gravity is a force, not a form of energy. Light, heat, and sound are all types of energy that can be transferred or converted, while gravity acts as an attractive force between masses.

What energy transfer occurs in a light bulb?

• motion --> electrical

• Chemical --> thermal

• electrical --> light --> heat

• KE --> Thermal

Answer explanation

In a light bulb, electrical energy is converted into light energy and heat energy. The correct sequence is electrical --> light --> heat, as the bulb emits light while also generating heat.

True or False: Heat transfer always occurs from cold to hot.

• True

• False

Answer explanation

False is correct because heat transfer occurs from hot to cold, not the other way around. This is a fundamental principle of thermodynamics.

Particle motion (kinetic energy) ________ when temperature increases.

• decreases

• increases

• stays the same

• disappears

Answer explanation

As temperature increases, particles gain energy and move faster, leading to an increase in kinetic energy. Therefore, particle motion increases when temperature rises.

Fill in the blank: Temperature is the measurement of ________ energy.

• kinetic

• potential

• chemical

• thermal

Answer explanation

Temperature measures the average kinetic energy of particles in a substance. Kinetic energy relates to the motion of particles, making 'kinetic' the correct choice. Potential, chemical, and thermal energies are different concepts.

What are atoms? Fill in the blank: Atoms are the ________ building blocks of all matter.

• largest

• heaviest

• smallest

• oldest

Answer explanation

Atoms are the smallest building blocks of all matter, meaning they are the fundamental units that combine to form everything around us. Therefore, the correct choice is 'smallest'.
