Hi, You should begin studying for the first exam scheduled for October 7. Also HW #2 is due Sept. 30 at 11 am in lecture. Have a nice weekend. Mrs. Deming Lecture Summary (9/21 and 9/23) Newton’s three laws of motion were enhanced through demonstrations. Examples of interia were given. The combination of the Moon's inertia (to continue to move in a straight line) and the Earth's gravity on the Moon (the Moon is accelerated toward the Earth) results in a stable orbit. Newton's law of gravitation was combined with his second law of motion to show that all bodies fall to Earth in the same manner, their mass or weight doesn't matter. Newton's third law is referred to as the “action/reaction” law of motion. Weight is a measure of gravitational force on a mass. On the surface of a planet, gravitational force, or weight, depends on mass divided by the radius squared. Demonstrations were done to illustrate many aspects of Newton’s Laws. The basic characteristics of the Solar System were listed.
