What type of energy is possessed by a moving car?
Kinetic energy
Radiant energy
Potential energy
Thermal energy
A moving object possesses kinetic energy, which depends on its mass and velocity. The faster or more massive the object, the more kinetic energy it has. Stationary objects do not have kinetic energy. For more details, see https://en.wikipedia.org/wiki/Kinetic_energy.
What type of energy is stored in an object due to its height above the ground?
Which energy type is primarily associated with the random motion of atoms and molecules?
Thermal energy
Radiant energy
Chemical energy
Electrical energy
Thermal energy refers to the internal energy in a system due to the random motion of its molecules. As temperature increases, molecular motion increases and thermal energy rises. It’s often experienced as heat. Learn more at https://en.wikipedia.org/wiki/Thermal_energy.
What type of energy is carried by electromagnetic waves, such as visible light?
Radiant energy
Sound energy
Mechanical energy
Chemical energy
Electromagnetic waves transmit radiant energy as they propagate through space or materials. Visible light, radio waves, and X-rays are all forms of radiant energy. It does not require a medium to travel. For further reading see https://www.energyeducation.ca/encyclopedia/Radiation.
If the velocity of an object doubles while its mass remains constant, what happens to its kinetic energy?
Which energy transformation occurs in a battery-powered flashlight when it is switched on?
Chemical energy to radiant energy
Radiant energy to chemical energy
Potential energy to kinetic energy
Thermal energy to chemical energy
In a flashlight, stored chemical energy in the battery is converted into electrical energy and then into radiant energy (light). A small amount also becomes heat. This sequence highlights multiple energy transformations. Read more at https://en.wikipedia.org/wiki/Flashlight#Operation.
Sound energy travels through materials as what type of waves?
Mechanical waves
Electromagnetic waves
Nuclear waves
Thermal waves
Sound propagates through substances via mechanical waves, which require a medium to travel. These waves are longitudinal, moving particles back and forth in the direction of wave travel. Sound cannot move through a vacuum. More info at https://en.wikipedia.org/wiki/Sound.
What type of energy is stored in the bonds of chemical compounds?
Chemical energy
Potential energy
Kinetic energy
Nuclear energy
Chemical energy is stored in the bonds between atoms in molecules. When these bonds break or form, energy is absorbed or released. This is the basis of chemical reactions, such as combustion. Learn more at https://www.energyeducation.ca/encyclopedia/Chemical_energy.
Which of these is an example of nuclear fusion?
Combining hydrogen nuclei to form helium in the Sun
Splitting uranium atoms in a nuclear reactor
Radioactive decay of radium
Burning coal to produce steam
Nuclear fusion is the process where light nuclei combine to form a heavier nucleus, releasing energy. This occurs in stars like the Sun when hydrogen fuses into helium. It is different from fission, which splits heavy atoms. See https://en.wikipedia.org/wiki/Nuclear_fusion for more.
Gravitational potential energy near Earth's surface is given by mgh. Which factor does NOT affect it?
What energy conversion occurs in the photoelectric effect?
Radiant energy to kinetic energy
Chemical energy to electrical energy
Nuclear energy to radiant energy
Potential energy to mechanical energy
In the photoelectric effect, photons (radiant energy) strike a material and eject electrons, converting the light energy into kinetic energy of electrons. This phenomenon helped establish the particle nature of light. More details at https://www.britannica.com/science/photoelectric-effect.
Which substance has the highest specific heat capacity, requiring the most energy to raise 1 kg by 1°C?
Water
Iron
Aluminum
Copper
Water has a high specific heat capacity of about 4184 J/kg·°C, meaning it takes more energy to raise its temperature compared to most other substances. This property helps moderate Earth's climate. Metals like iron and copper have much lower values. See https://en.wikipedia.org/wiki/Specific_heat_capacity.
What type of energy is associated with the deformation of an elastic object, like a compressed spring?
Which process releases alpha particles from an unstable nucleus?
Alpha decay
Beta decay
Gamma decay
Nuclear fission
Alpha decay is a type of radioactive decay where an unstable nucleus emits an alpha particle (two protons and two neutrons). This reduces the atomic mass and changes the element. It is common in heavy isotopes like uranium. See https://en.wikipedia.org/wiki/Alpha_decay for more.
According to Einstein’s mass–energy equivalence (E=mc²), what happens to mass when energy is released in a nuclear reaction?
Mass decreases
Mass increases
Mass stays the same
Mass is fully converted into energy
Einstein’s equation E=mc² shows that a small amount of mass can convert into a large amount of energy. In nuclear reactions, some mass is lost (mass defect) and released as energy. This mass decrease is measurable. More details at https://www.britannica.com/science/mass-energy-equivalence.

Cheat Sheet
Kinetic Energy -
Kinetic energy is the energy of motion, quantified by Ek = ½ m v² (MIT OpenCourseWare). For example, a 2 kg object moving at 3 m/s has 9 J of kinetic energy. Use the mnemonic "half mass, velocity squared" to recall the formula.
Gravitational Potential Energy -
Gravitational potential energy depends on an object's height: Ep = m g h (NASA's educational resources). A 5 kg mass lifted 4 m stores 5×9.8×4 ≈ 196 J of energy. Remember "mighty hills give potential thrills" to lock in m g h.
Thermal Energy -
Thermal energy stems from random molecular motion and follows Q = m c ΔT, where c is the specific heat capacity (University of Cambridge). Heating 1 kg of water from 20 °C to 30 °C takes about 42 kJ. The phrase "Q equals mass times capacity times delta T" makes it stick.
Radiant Energy -
Radiant energy is carried by electromagnetic waves, with photon energy given by E = h f (Planck's constant h ≈ 6.63×10â»Â³â´ J·s). Visible light in the green region (≈5.5×10¹ⴠHz) has about 3.6×10â»Â¹â¹ J per photon. Recall ROYGBIV to map wavelengths to energy levels.
Chemical Energy -
Chemical energy is stored in molecular bonds and quantified by enthalpy change ΔH (IUPAC standards). Burning 1 mol of methane releases about - 890 kJ of energy. Think "break to take, form to warm" to remember bond energy trends.
