Vector Man rescues a waiter from a burning restaurant, but forgets to put out the fire! This lesson will explain how to draw free body diagrams.<br/>
Definitions included: free body diagram, net external force

Vector Man rescues someone who is having a heart attack! But he doesn’t take them to the hospital… This lesson will apply Newton’s 1st Law of Motion to stationary, moving and accelerating objects.

Definitions included: net external...

It’s no surprise that forces are everywhere! But how do we work out which forces are important, and which ones can be ignored? This lesson will distinguish between external and internal forces, before diving into more examples of contact...

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...

Howcast - Learn how to do side bends, an advanced Pilates Mat exercise, from Core Pilates NYC instructor Sarah Ruback in this Howcast workout video.

A moving object doesn’t always have a force in the same direction as its motion. Learn why with this simple hockey puck example and deepen your understanding of Newton’s laws.

All is quiet inside the anthropology and archaeology museum… until Carmen strikes again! This lesson will apply Newton’s 2nd Law of Motion to moving and accelerating objects.

Definitions included: Newton’s 2nd Law of Motion,...

Although the impromptu surgery was a success, Shannon is taken to the hospital. This lesson will define inertia and apply Newton’s Law of Inertia.

Definitions included: in
ertia
Misconceptions included: inertia is a force,...

If you've never had a migraine, you might think it's just a really bad headache. But if you've ever had them, or you know someone who does, you know that they're much worse -- and much more complicated -- than that. Hank explains the...

This is how you include air resistance in projectile motion. It requires the Drag Force and Numerical Modeling (or the Euler Method). It is also very helpful to use a spreadsheet to do the calculations. I prove a statement from a...

Defining Force. Including its dimensions, demonstrations of force and mass affecting acceleration, showing that a force is an interaction between two objects and contact vs. field forces.

Before you can start learning about Forces and Newton’s Laws of Motion, you need to understand inertia and mass. This video defines both and more specifically inertial mass.

In the millions of years since oxygen began saturating Earth’s oceans and atmosphere, most organisms have evolved to rely on this gas. However, there are some places where oxygen-averse microorganisms like those from Earth’s earliest...

Howcast - Learn how to do a tsuki komi block from Sensei Oliver Martin in this katana sword fighting video from Howcast.

Struggling with forces and Newton’s Laws in AP® Physics 1? In this lesson, we clear up some of the most common stumbling blocks from roughly the first half of Unit 2, including center of mass, translational equilibrium, constant velocity...

Explore the unexpected link between Abraham Lincoln's beard change and Milton Bradley's shift from lithographs to creating the iconic board game, "The Game of Life."

How well do you know your bass clef ledger lines above and below the stave? You may be fairly new to reading music or you may have been a musician for years but many musicians get caught out when it comes to reading notes on ledger...

We use Newton’s Second Law and Uniformly Accelerated Motion to experimentally determine the Static Coefficient of Friction between Tires and Snow.

In this video, the teacher explains how to multiply a fraction by a mixed number using visual representations. The lesson begins with a review of fractions and their parts, the numerator and denominator.

The video is a lesson on Newton's three laws of motion. It explains each law and provides examples to illustrate them. The video provides calculations to demonstrate the second law and gives examples of interactions between objects to...

There are telltale signs of bad leadership. We look at 9 qualities of bad leaders from Johnson and Hackman's book on leadership.

In this video, we talk about the process of generating a story for manga or comics, discuss the importance of having a central idea or theme and building the story around it. It also explains how to develop characters, create plot twists...

As Psychology is a science, it uses the experimental method in a similar way to Physics, Chemistry and Biology. However, because of the subject matter Psychologists are studying, it can sometimes seem a bit confusing.
