A clear explanation of Newton's First Law of Motion, the law of inertia, with diagrams and real-world examples. Useful for both students and teachers. Written by a high school physics teacher.

This resource provides a discussion of Newton's Laws of Motion.

Learn more about finding acceleration through the practices found in this lesson. "The process of determining the acceleration of an object demands that the mass and the net force are known." Check out this comprehensive site.

Step-by-step illustrated instructions showing how to drop four eggs into four cups without touching them. Demonstrates the concept of inertia according to Newton's first law of motion.

This is part of a lesson on Newton's Laws of Motion that focuses on inertia and mass. It restates Newton's first law of motion. The lesson also gives a helpful visual description concerning friction.

A demonstration that will grab students' attention to learn about Bernoulli's principle and Newton's Laws of Motion.

Introduce students to the ideas of motion and force in this hands-on lesson plan.

This activity provides students an opportunity to investigate Newton's first law by observing inertia in a variety of experiments. Students will hypothesize on possible outcomes, write observations of what has happened, and apply...

This study guide on gravitation covers some key vocabulary, Kepler's Laws of Planetary Motion, and orbiting bodies or satellites. Includes important equations. It is available for download with free registration.

Students' use a motion detector to examine how different types of motion affect the shape of the distance versus time plot. They explore how changes in direction and other factors affect the shape of the plot.

A series of graphics, downloadable animations and text describe and explain the motion of a pendulum. Some sections require an understanding of calculus.
