Yurt force circle and pulleys
Unit five centers on Newton's laws, force, and a simple pulleys experiment that leads once again to a linear relationship. The morning lecture-demonstration ended with a yurt force circle to demonstrate Newton's third law that every force has an equal and opposite counter-force.
