Loos-en-Gohelle, a former mining town in northern France, has transformed into a model for sustainable development under the leadership of Mayor Jean-François Caron. By investing in green initiatives like photovoltaic solutions, even...

What are the different wavelengths of the electromagnetic spectrum? When seen, what can invisible light reveal? What discovers has the VLA found so far? How do astronomers spend their time?<br/>
The Very Large Array Telescope, Part 2

Paul Andersen introduces forces, motion, and Newton's three laws in this video. He begins by describing forces as pushes or pulls on objects that produce motion. A lack of motion results from a balanced set of forces. A teaching...

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...

👉 Learn all about sequences. In this playlist, we will explore how to write the rule for a sequence, determine the nth term, determine the first 5 terms or any term of the sequence. We will investigate binomial expansion as well as...

Jump on your skateboard and learn how to skate like a scientist! How can we speed up? How can we slow down? Investigate what happens when we push different objects. Discover the wonders of force and motion with Nala and Lorenzo!

Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to...

In this video Paul Andersen explains how a net torque acting on an object will create rotational motion. This motion can be described by the angular displacement, angular velocity, and angular acceleration. The linear velocity can be...

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...

In this video Paul Andersen explains how the work is a product of the external force applied to an object or system and the distance it moves. Power is a measure of the amount of work done per unit time. The work can be calculated as...

This is a lecture video on Newton's second law and momentum, where the relationship between the change in momentum of an object and the resultant force acting on an object is explained. The video covers the derivation of the equation F =...

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...

The urge to jump or high place phenomenon apparently springs from a distortion of our perceptions. Lab tests have shown that people estimate disgusting things, such as feces, to be closer than they really are. Another example is...

Explore how the gravitational force and potential energy behave along the central axis of a planet’s ring system. Learn how symmetry simplifies the math and how energy conservation reveals the particle’s speed through the ring’s center.

Real World Science: Force is one of a series of videos that encourages children to explore the world of science in their immediate surroundings. Through observation and experimentation, students will learn properties of forces, Newton's...
