Sandy uses a grocery cart when in Publix, She is pushing 12 kilograms of groceries a distance of 6 meters with a force of 25 Newtons. How much work does she do?
Work = Force x Distance
150N・m or 150J
400
Between which two points are kinetic energy and potential energy completely transferred?
A-B or B-D
500
What is energy?
The ability to do work or cause change.
500
The Law of Conservation of Energy
We can neither create nor destroy energy. (Just change it)
500
These three types of energies are considered Kinetic and Potential.
Thermal, Mechanical, and Electrical

Richard was at IKEA buying a new dining room table. He wished to know how much power it took him to move it from the store to his car. If it took him 120 seconds to apply a force of 490 Newtons over a distance of 10 meters, how much power was used?
490N*10m
------------ = 41watts
120 sec

As a candle burns on a table, you can see the electromagnetic energy and feel the thermal energy released. Explain what is happening with the energies.
the total chemical energy equals the electromagnetic and thermal energy released from the candle.
the total amount of all types of energy is conserved when the candle burns.
