Physics - Unit 5

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:

  • Determine the stored energy in a spring.

  • 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.

Homework

I am out with the Robotics team. You will be given a handout. You may work with another person, but your answers may be different. I am grading for correct answers.

Additionally, we will be using the information that you learn through this activity. It is important that you read and comprehend the instructions and given information.
