The Physics Classroom: Newton's Laws: Newton's Second Law

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

Here is an unusual comparison: the swimming conditions of a sperm cell and a sperm whale. Introduce your physics class to the Reynolds number by sharing this video comparison during your fluid mechanics unit. Afterward, teach them to...

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

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

Through illustrated examples and interactive practice problems, students find the value of forces acting upon objects using force equations.

Use this outline to find out about Newton's Laws of Motion. Use the different lesson plans covering the laws of motion to learn more.

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

Students learn the basics of the law of inertia with this short tutorial and accompanying animation which demonstrates the motion.

Students are give the opportunity to practice some action-reaction pair problems. Each example is self-checking for on-the-spot reinforcement.

This interactive physics tutorial introduces the basic meaning of force, including contact and non-contact forces.
