Description

The simulation shows the flow of energy for a block that is connected to a pulley by a string wrapped around the outside of the pulley. The subscript 1 refers to the block, and 'p' refers to the pulley. You can view the energy from five different perspectives, ranging from defining the system to be the Earth and the block and the pulley, to just the block or just the pulley.

Note that the simulation uses 10.0 m/s/s for g.

See if you can make sense of all the different perspectives on energy. Note that the system starts from rest. In some views, you see the work done by gravity on the block or the work done by tension on the block, or on the pulley. The labels are either above or below the bars, not beside them. U is gravitational potential energy, W is work, and K is kinetic energy.
