Hi Folks,
Today we got into the concept of Potential and Kinetic energy and how they change into each other. We also discussed energy efficiency and conservation of energy.
For homework this week:
Find the energy the ramp stole from the ball (if you haven't already finished that in class).
Find the energy efficiency of the ramp. Take the work out (the energy the box was hit with) divided by the work in (the potential energy the ball started with) and multiply that by 100 to convert it to a percentage.
Read the Potential and Kinetic Energy chapter in the eBook
Open the following simulation and use it to answer the following questions in the .pdf.
