Today, February 3rd, in Physics class we did the following:

-Passed back papers -Reviewed midterm questions -Daily Question -Energy Notes

REMINDER: Don't forget that some people still owe money towards the MTHS Physics t-shirt. Long- $9.65 Short-$6.90

At the beginning of class, you were supposed to pick up page eleven, twelve and thirteen. Following that, Mr. Manning handed back graded papers. You should have received a graded daily question and The Ten Most Missed Midterm question paper. Once that was completed, as a class, we went over the Midterm question worksheet to find the right answers. Make sure to correct any wrong answers so there is a better understanding for later use. After our review, we began to work on page eleven, Types of Energy, Some Examples, and Energy Transfers. We learned the following terms:

1. Mechanical - Energy created by pushing, pulling, friction, gravity, vibrations, ect. 2. Thermal- Sum of potential and kinetic energies of the molecules in a system. 3. Chemical- Energy is gained or released when chemical bonds are formed. 4. Radiant- Energy in form of visible and invisible light, x-rays, gamma rays, radio waves, microwaves, and all other forms of electromagnetic waves. 5. Electrical- Energy cause by the interplay of electrical fields between electrically charged praticles. 6. Magnetic – Energy cause by the interplay of magnetic fields between particles. 7. Nuclear – Energy due to the strong and weak nuclear forces in an atom.

This is the Types of Energy, Some Examples, and Energy Transfers paper we received.



Next, Mr. Manning explained our Extra Credit, Energy Transformations, due Friday. For the extra credit, you are to identify a device, phenomenon, process, or event whereby one form of energy is transformed into another.
