In which John Green teaches you about Nationalism. Nationalism was everywhere in the 19th century, as people all over the world carved new nation-states out of old empires. Nationalist leaders changed the way people thought of themselves...

Professor Dave explores the career and legacy of President Bush Jr

This problem is about using the Right Hand Rule to determine the net force on a current carrying loop next to a current carrying wire.

It explains the concept of force, net force, equal and opposite forces. It also talk about the resultant force and various effects of it.

Johann Becher, científico alemán del siglo XVII, avalo la teoría de que cuando las sustancias arden, liberan un elemento, que se bautizó con el nombre de flogisto. Se equivocaba, y su teoría errónea hizo que muchos químicos no...

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,...

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...

An important review highlighting differences between the equations for Conservation of Momentum, Impact Force and Impulse.

When a point particle collides with a rigid object with shape which is allowed to rotate on a stationary axis, is linear momentum of the system conserved? Is angular momentum of the system conserved? These questions are answered using...

In this video Paul Andersen explains how forces on an object always require another object. An object cannot exert a force on itself. If net forces on an object are balanced the object will remain at rest or move with a constant...

If you've heard of Toxic Shock Syndrome, you might think you can only get it from tampons, but the bacteria that cause this problem are surprisingly common and we still don't know why they sometimes turn deadly.

You’ve probably heard about how the extinction of honeybees will lead to some sort of bee-pocalypse doomsday scenario for humanity. But what would actually happen if all the honeybees went extinct?

Want to learn more about the topic in this week's video? Here are some key words/phrases to get your googling started: - Lifting Condensation Level (LCL): The altitude at which the water vapor in rising air begins to condense - Adiabatic...

In this video Paul Andersen explains for the position of an object over time can be used to calculate the velocity and acceleration of the object. If a net force acts on a object it will experience an acceleration.

Did you know that Gwen stacy's death and Newton’s second law of motion have a connection? In the comics “The Amazing Spiderman”, Gwen Stacy dies after she is pushed off a bridge. Spiderman jumps behind her to catch her in his webbing,...

This video explains the concept of force as a vector quantity with defined direction and magnitude. It demonstrates how forces in opposite directions cancel each other out, and how the parallelogram law of vector addition can be used to...

SchoolOnline's Secondary English videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key skill in English Reading and Writing that students need to master in clear and easy to...
