Honors Physics - Unit 4

Work and Energy

This unit focuses on the ideas of work and energy. We will learn what physicists mean by “work.” and how work changes the energy of an object though the Work-Energy Theorem we will use the Law of Conservation of Energy to show how energy is always conserved in a system but can change forms.

BY THE END OF THIS UNIT, you should be able to:

  • define work and energy

  • calculate an object’s kinetic and/or potential energy.

  • use the work energy theorem to solve problems and understand the connection between work and kinetic energy.

  • Use the Law of Conservation of Energy to solve problems in which energy is conserved but changes form.

  • understand how to use components in the x- and y-direction to calculate forces on an inclined plane

I will be out this day.

Please watch these videos and take notes / work the problems….I know it looks like a lot. I watched them and did not die. It’s about 30 minutes total. You can do this!
