This physics video tutorial explains kepler's third law of planetary motion. It provides physics problems where you have to calculate the period of Mars or the distance between Venus and the Sun using the orbital radius of earth and sun-earth mean distance. This video also provides the formula needed to calculate the mass of the sun.
