Q Part 1: Specify why the telescope was such an important factor for proponents of the Heliocentric cosmogony. Then, pick one of Galileo's discoveries and explain exactly why it was such an effective case against ancient Greek philosophy. Part 2: First, pretend that the planet Venus has a perfect circular orbit around the Sun and travels at exactly 35 km/s. According to Newton's 1st Law does this mean that no force is acting on Venus? Explain your reasoning. Next, step away from the computer and move in a straight line for a few meters, then come back and explain the details of what occurred in terms of Newton's 3rd law of motion. Bonus (+2 points): Galileo's experiment on falling bodies began with a motionless ball set atop an inclined plane, name the force that must always be present for it to always accelerate downward.
