Friction Block Features
The Friction Block is constructed of wood covered with felt on two sides. Each side has a
different surface area to measure the effect of surface area on frictional force. The block
is designed to fit into the tray of a dynamics cart so that the cart can move on its wheels
or turned upside down to move on the Friction Block without changing the mass.
