Energy Notes
1. Energy is the ability to do work or the ability to make things change.
2. Energy occurs in two main types: potential and kinetic.
3. Kinetic energy = energy of motion found in objects or substances. Only moving objects have kinetic energy.
4. Potential energy = energy due to the relative position of an object or substance.
5. Which stack of books has a higher potential
6. Which rubber band has a higher potential energy
energy in the image below: book A or book B?
in the images below: rubber band A or rubber band B?
A
A
B
B
7. Which molecule below has a lower potential
8. Potential energy can be converted
energy: the carbon dioxide or the glucose (sugar).
into kinetic energy and kinetic energy can be
converted into potential energy.
9. Potential energy in a battery can be
glucose (sugar)
carbon dioxide
converted into kinetic energy in an
electric motor.
10. Kinetic energy in a windmill can be converted into potential energy as it charges stored batteries.
11. Energy may change from one form to another, but the amount of energy stays the same
12. The transfer from potential to kinetic energy occurs when an object is in motion.
13. The transfer from kinetic to potential occurs when an object transfers from a moving object to an object in a
position with potential energy.
14. A roller coaster is a good example of the transfer between potential and kinetic energy.
15. Falling object: Potential energy_____, kinetic energy _____
16. Object being raised (elevated): Potential energy _____, kinetic energy _____
Conduction, Convection, and Radiation Notes
1. List some forms of energy:
potential, kinetic, thermal, chemical,
2. Heat is given off when an object’s
thermal energy is transferred.
gravitational, elastic
3. Thermal energy can be transferred in 3 ways: conduction, convection and radiation.
4. Radiation is the transfer of energy by waves.
5. Conduction is the transfer of heat energy by direct contact between particles.
6. Convection is the transfer of heat energy through liquids and gases by moving particles.
7. Label conduction, convection, and radiation in the image below.
conduction
convection
radiation
