Gravitational Potential Energy

In our investigation, we found that we needed to know how to calculate the Gravitational Potential Energy of the swinging mass. Mr Nicoll gave a quick overview of how to do this, using a diver on a board as a context:

The key thing to note is that all units need to be converted to SI Units (kg for mass, m for height).

From this information, we could actually calculate the speed the diver hits the water at (assuming no energy was "lost" due to friction during the dive). This will be covered in tomorrow's lesson.
