Friction is an inevitable phenomenon. Without friction, it would be impossible to walk or drive
cars. However, friction is also the cause of energy loss and we would like to reduce it for higher
efficiency in machines. In this experiment, we will study the force of friction as an object is
stationary and in motion. We will calculate the coefficients of static and sliding friction using
video motion analysis.
