I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Have you ever looked up at the moon and wondered why it looks different every night? Learn about the moon's orbit and the lunar cycle with a reading comprehension exercise. Using context clues, kids find the definitions of unfamiliar...

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...

Getting the right measurements can save a lot of time and money in the real world. Learners are introduced to unit conversion and how to accurately go from one unit to another. The first pages are notes and then the packet finishes with...

In this earth science worksheet, learners complete a series of multiple-choice and short-answer questions on the different moon phases, gravitational pull, and the Earth's layers.

Develop an understanding of the universe. Learners answer 10 multiple choice questions about several topics in astronomy. Questions contain information about the age of the universe, gravitational attraction, galaxies, planets and comets...

For this eighth-grade science standardized test practice worksheet, learners answer 79 multiple-choice and short-answer questions to review their science knowledge.

In this eighth-grade science standardized test practice activity, pupils answer 78 multiple-choice and short-answer questions to review their knowledge.

For this fourth-grade science standardized test practice activity, fourth graders answer 42 multiple-choice and short-answer questions to review their science knowledge.

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.

This lesson explains how the moon affects tides on Earth and about the different types of tides.

A short description of how Cavendish measured the value of G - the universal gravitation constant and supported Newton's theory. Illustrated.

Students enter their weight here on Earth, and find out how much they would weigh on the moon and other planets.

By the end of this section, you will be able to explain Earth's gravitational force, describe the gravitational effect of the Moon on Earth, discuss weightlessness in space, and understand the Cavendish experiment.
