Physics P1 AQA

Sorry for a bit of a re-post but this went in the wrong section.

What equations do we need to know for tomorrow that aren't on the physics equation sheet for AQA P1?

Thanks :smile:

I'm sorry nobody has mentioned it but you should know how we calculate the payback time.

Just remember this:
Payback time = cost of installation / saving per year

Draw the first arrow-liney-ray thingy that enters the block at the same angle as the angle of incidence. Make it straight with a ruler and draw it until you hit the bottom edge of the block and have an arrowhead in the middle. Then draw one joined to it coming out of the bottom at an angle, a bit like you've drawn it in your photo.
