Today we very briefly talked about machines and efficiency.
Notes: Machines
Your homework is a little half sheet called HW: Machines. I checked your Energy of a Bouncing Ball Lab while you started that homework.
On Monday/Tuesday nest week you will be completing a lab. The goal is to find the frictional force on a cart rolling up/down a ramp, plus find the efficiency of said ramp. How you do these two things is up to you, so start thinking about it over the weekend.
