The friction lab was designed to show the effects different surfaces have on the motion of an object and the distance traveled, the force remaining constant. The objects were hard and smooth, or hard and rough, or soft and smooth, or soft and rough. The distances traveled with each type were measured a number of times and averages determined. The results were analyzed and questions answered at the completion of the exercise. Once back in the classroom, the concept of distance forces was introduced, with the 3 major forces outlined. The force of gravity was briefly introduced.
