Kepler's 3rd Law

High school physicists apply their knowledge of planetary motion. Using Kepler's three laws, Newton's law of universal gravitation, and the provided properties of the moon, sun, and Earth, they proceed to solve 23 problems. An answer key...

Discover the transition from circular orbit theories to elliptical orbits. An episode of a video series on astronomy models the different elliptical shapes of the orbits of the planets in the solar systems. Using string, the presenter...

Introduce your physics or astronomy class to Kepler's laws of planetary motion with this straightforward worksheet. It covers the basic concepts of each and has learners answer questions to demonstrate their grasp on them. You could use...

Young scholars examine the orbits of the more than 1,400 satellites that orbit Earth and visualize the application of Kepler's laws. They observe patterns of orbital periods and velocity as a function of distance from Earth to facilitate...

In the following interactive students will begin to understand the laws of Kepler regarding planetary motion and derive the third law of Kepler for circular orbits. They will also discuss the Ptolemaic model of the universe.

By the end of this section, you will be able to state Kepler's laws of planetary motion, derive Kepler's third law for circular orbits, and discuss the Ptolemaic model of the universe.

A flipped classroom lesson introduces astrophysics fanatics to Kepler's three laws of planetary motion. After reading about the laws of ellipses, equal areas, and harmonies, and also learning how Newton's gravitation concepts come into...

Common sense says that the farther a planet is from the sun, the longer the orbit. Kepler turned common sense into his third law by quantifying this relationship. Classes explore Kepler's Third Law through an interactive tutorial. They...

Kepler decided to think outside the box and discovered that planets orbit in elliptical patterns. An engaging activity demonstrates the elliptical orbit pattern in relationship to the area of a planet to explain Kepler's Second Law....

Why does it take Pluto 90,000 days to orbit the sun, but it only takes Mercury 88 days? An interactive lesson helps pupils find a connection between the speed of orbit and distance a planet is from the sun. The simulation allows for...
