In this math worksheet, students determine if the information is used to describe a line. They examine the parametric and symmetric equations.

In this math worksheet, students investigate how time is related to the concept of increasing or decreasing velocity. Then they consider times and answer the questions of whether the velocity is changing.

In this motion instructional activity, students calculate the initial angular acceleration, and the angular speed before and after impact for different objects. This instructional activity has 3 problems to solve.

In this planet science activity, students learn 6 facts about the planet Uranus. Students also read a paragraph containing more information about the planet.

Move the sun, earth, moon, and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it.

An interactive simulation that teaches about gravitational force, circular motion, and astronomy by manipulating the sun, earth, moon, and a space station to observe the effects of gravity and orbital paths. This simulation can either be...

Through illustrated examples and interactive practice, students explore Newton's ability to relate the cause for heavenly motion (the orbit of the moon about the earth) to the cause for Earthly motion (the falling of an apple to the...

Students explore how a satellite's motion is governed by the same physics principles and described by the same mathematical equations.

Use this site to learn how the Earth's not-so-circular orbit around the sun has affected our climate over thousands of years, and continues to affect our climate now.

Describes the logic behind the development of Newton's law of universal gravitation. Beginning with Johannes Kepler and his three laws of planetary motion, content walks the reader through Newton's thought process and development of this...
