A birthday party isn’t complete without cake, music and drama! This lesson will introduce the most common types of contact forces encountered in Physics.

Definitions included: contact force, normal force, friction force, static...

10 trials to calculate the coefficient of static friction and how to calculate the uncertainty of this measurement.

At the 2014 Olympics, long track speed skater Shani Davis will be wearing what may be one of the most advanced competition suits ever engineered. Under Armour Innovation lab's Kevin Haley and polymer scientist and engineer Sarah...

In this video, students will learn about six simple machines: lever, inclined plane, wedge, wheel and axle, pulley, and screw. They will understand the basic principles of how these machines work and how they can make our lives easier by...

Billy analyzes ABS brakes to show the difference between Rolling without Slipping and Rolling with Slipping. He also answers the question in the title of the video, but why would I write that in the description?

Derivation of Pendulum equations method 1

Kinetic energy and elastic potential energy as functions of time graphs for a horizontal mass-spring system in simple harmonic motion are demonstrated. Conservation of energy is shown.

This video explains the concept of charging by friction. The video presents experiments and demonstrations to show how two insulators become charged and how opposite charges attract while like charges repel each other. The video also...

Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about electric circuits.

NIST materials scientist John Royer explains the science behind “oobleck” – and other shear-thickening fluids – in this NIST in 90 (seconds) video, potentially putting an end to a long-running scientific debate. Royer is the lead author...

This video explains the concept of work and energy transfer when a force is used to displace an object. The video demonstrates how to calculate work done and the energy transferred in different situations. The video provides examples...

This video explains the variability of skin thickness in different parts of the body and how it affects the aging process. It also discusses the impact of gender and ethnicity on skin thickness and its implications for cosmetics, plastic...

Curling has been in the Winter Olympics for four years now, but it still seems a little strange to most of us. John Shuster, the captain--or "skip"--of the U.S. Curling Team in Vancouver, explains this unusual sport, and NSF-funded...

Spinning toys and tops have unusual behaviors. The famous tippe top flips itself over and spins on its stem. The PhiTOP stands up on its end, which you can also do with a hard-boiled egg. These behaviors all have to do with torque and...

How to find the minimum coefficient for an object to roll without slipping on an incline.

Friction always creates heat. Brakes and tires depend on friction to work, but more friction isn't always better. In the engine, friction is never good and engine builders use everything from oil to high-tech coatings to get a little...

This video explains the difference between electrical conductors and insulators, and how insulators can be charged by friction. It goes into detail about the movement of electrons and how charges can be conserved. The video also...

This video is a lesson on free body diagrams. It explains what free body diagrams are, the steps involved in making them, and how to use them to analyze both static and dynamic situations. The lesson also covers how to apply Newton's...

Just an intro into friction.

Balanced & Unbalanced Forces | Forces & Motion | Physics | FuseSchool How do we find out whether the forces acting on an object are balanced or unbalanced? Learn in this video from the "Forces and Motion" chapter of the FuseSchool GCSE /...

Circular motion is quite self-explanatory really; it’s simply the physics behind things moving in circles. When something moves in a circle it’s velocity is constantly changing, even if its speed is constant. This is because velocity is...

The free body diagram we first learn is not entirely accurate. All of the forces are not drawn from the center of mass of the object. Learn why we start this way and, when we get torque, what the free body diagrams will actually look...

Mr.p pushes a shopping cart so you can learn about the physics concept of work!

Bobby teaches the basics of friction and the differences between Static and Kinetic Friction.
