Transfer and Transform
When energy moves from one object to another, such as from a hot stove to a pot of water, this process is called energy ________.
What is transfer?
This type of potential energy is stored in an object when it is lifted above the ground.
What is PE
This is the energy that an object possesses due to its motion.
KE

Jordan wants to know the difference between using a 60-W and 100-W lightbulb in her lamp. She calculates the energy it would take to use each bulb for 30 s by using this equation:
Power = Energy transferred (J)/time (s)
What is the difference in the amount of energy transferred by the two bulbs during this time?
1200J
