Energy and Power

Different Day

Today I am in a virtual conference. You will be working on your own. I am providing notes for you in order to complete the assignment. If you have questions feel free to ask, I am never to busy to pull away and help you.

Journal - What is the difference between kinetic and potential energy?

Equations to use

Work - Energy Theorem - W = ΔE

 $Power\ =\ \frac{\Delta E}{t}$  

 $Power\ =\ \frac{W}{t}$  
Energy and Work are both measured in Joules (J) and Power is measured in Watts (W)

Two more equations to consider

Kinetic Energy (KE) - KE = 1/2mv²

Translational Kinetic Energy = KE_trans = 1/2mv²

The difference is that translational kinetic energy comes from the center of gravity of an object.

Practice Problems

Your choice! Google Classroom or Paper Handout.
