Gravitation Virtual Lab
This presentation will provide you with a quick review of Kepler’s Laws of planetary motion as well as an exploration of Newton’s Universal Law of Gravitation. I hope that you learn something. Enjoy!

Johannes Kepler (1571  1630) 3 Laws of planetary motion Kepler didn’t understand WHY the planets moved as they do, but he did discover the manner in which they move. He described their motion in 3 laws…click on the links (use your ear buds) to learn about (and take notes on)… 1. First Law - Planets travel around the Sun in elliptical paths with the Sun at one foci. Foci – the two points that define the shape of the ellipse. One is the Sun…what’s the other??? (Kind of a trick question)

First Law link: Planets travel around the Sun in elliptical paths with the Sun at one foci. 2. Second Law link: - A line from the sun to a planet will sweep out equal areas in equal time periods. 3. Third law link: - The larger the orbit of a planet, the longer it takes to complete a revolution. The videos are on YouTube… if you can’t watch them at school then watch them at home.

Issac Newton ( ) Among other things, he devised his law of Universal Gravitation – this is HUGE! We will take notes on this in class this week. In the meantime… …explore the following virtual lab to see if you can discover the main idea of the law. Work with your lab partner to answer the questions on your lab worksheet as you explore the virtual lab.

Thank you.
