Finding Unknown Masses
Image:masses.JPG In this experiment the masses of two rocks can be determined by using the idea of forces in equilibrium. The data is collected and then you are required to do the calculations to find the masses.

Angle of Friction Experiment
Image:friction1.jpg The coefficient of friction for a body on an inclined plane can be found by looking for the angle at which the body is on the point of sliding down the slope. This experiment shows how the coefficient of friction between a calculator and a wooden plane can be found.
