The Physics Classroom: Newton's Laws: Finding Individual Forces

Through the use of free-body diagrams and Newton's laws, students analyze the motion of two objects together.

This physics tutorial provides students some practice using a given equation to find the acceleration of an object.

This interactive tutorial gives an in-depth introduction to a variety of forces; both contact, and non-contact.

A four-lesson e-textbook covering topics in Newton's Laws. Tutorials include informational text,animations, interactive activities, and quick, interactive comprehension checks throughout the lessons.

States the equation of Newton's law of universal gravitation. States the value of G and uses the equation to solve problems.

Have you ever felt that queasy feeling in a moving elevator? Explore the physics behind the sensations of weightlessness and weightiness. Teacher notes and a downloadable handout are also provided.

In this illustrated introduction of Newton's Laws of Motion, the ways in which motion can be explained will be discussed.

Students begin to explore the meaning of Newton's Second Law of Motion by doing several self-checking practice problems.

While most people know what Newton's laws say, many people do not know what they mean. This tutorial allows students the ability to understand their meaning and to believe their implications.

Through illustrated examples, and interactive practice problems, students examine Newton's Third Law of Motion.
