We reviewed and discussed the homework questions. We discussed through a series of questions that an object at rest and an object moving both show motion. I showed that friction works in opposition to movement and will eventually stop a moving object. In order to keep an object moving, a force must be constantly applied, but what if friction was not present. Galileo's Theory of rolling a ball down an inclined plane with the second side decreasing in vertical angle was whiteboarded. The conclusion was drawn that the ball would roll without stopping if the second ramp was parallel to the table, and friction did not exist. A cup and a coin placed on an index card was used to arrive at Newton's first law.
