David explains how to use Newton's second law when dealing with multiple forces, forces in two dimensions, and diagonal forces. Created by David SantoPietro.

David explains some of the common misconceptions in dealing with Newton's Third Law. He also shows how to correctly and reliably identify Third Law force pairs. Created by David SantoPietro.

Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

In this video lesson, the concept of momentum applied to hard-body collisions is explained using a number of simple demonstrations, all of which can be repeated in the classroom. Understanding Newton's Laws is fundamental to all of physics, and this lesson introduces the vital concepts of momentum and energy, and their conservation. Only some preliminary ideas of algebra are used here, and all the concepts presented can be found in any high-school level physics book. In terms of materials required, getting hold of large steel balls may not be easy, but large ball bearings can be procured easily. On the basis of what students have learned in the video, teachers can easily generate a large number of questions that relate to one's daily experiences, or which pose new challenges: for example, in a collision between a heavy and light vehicle, why do those inside the lighter one suffer less injury?

Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration. Created by Sal Khan.

This class is an introduction to classical mechanics for students who are comfortable with calculus. The main topics are: Vectors, Kinematics, Forces, Motion, Momentum, Energy, Angular Motion, Angular Momentum, Gravity, Planetary Motion, Moving Frames, and the Motion of Rigid Bodies.

Physics I is a first-year physics course which introduces students to classical mechanics. This course has a hands-on focus, and approaches mechanics through take-home experiments. Topics include: kinematics, Newton's laws of motion, universal gravitation, statics, conservation laws, energy, work, momentum, and special relativity.

These instructional videos, created by Barbara Gilbert at Central New Mexico Community College, covers physics concepts and certain practice problems in Chapters 1-17 of OpenStax's College Physics text.

This is a course for non-science majors that is a survey of the central concepts in physics relating everyday experiences with the principles and laws in physics on a conceptual level. Upon successful completion of this course, students will be able to: Describe basic principles of motion and state the law of inertia; Predict the motion of an object by applying Newtonęs laws when given the mass, a force, the characteristics of motion and a duration of time; Summarize the law of conservation of energy and explain its importance as the fundamental principle of energy as a –law of nature”; Explain the use of the principle of Energy conservation when applied to simple energy transformation systems; Define the Conservation of Energy Law as the 1st Law of Thermodynamics and State 2nd Law of Thermodynamics in 3 ways; Outline the limitations and risks associated with current societal energy practices,and explore options for changes in energy policy for the next century and beyond; Describe physical aspects of waves and wave motion; and explain the production of electromagnetic waves, and distinguish between the different parts of the electromagnetic spectrum.

Explore forces and motion as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces. Graphs show forces, energy and work.

David explains what rotational kinetic energy is and how to calculate it. Created by David SantoPietro.

David explains moment of inertia and the rotational version of Newton's second law and shows how to solve an example problem. Created by David SantoPietro.

This lab activity is an exploration of Newton's Three Laws, forces and energy. Students will design, build, launch and analyze rocket data.

Mike Rettberg demonstrates Newton's Laws to his 8th grade science class by rolling a cart containing an egg into a barrier and crashing it. In the process, students learn difficult terms that are reinforced by their discussion of which Laws they are seeing in action.
