This video discusses the principle of force and the application of Newton's Three Laws of Motion. Students will witness the effect of friction on force and see how force is calculated. Other terminology includes: inertia, weight, mass,...

1) Calculating if our answer makes sense. 2) Why can’t we sum the torques on everything? 3) Finding the force of tension.

Learn how to calculate the buoyant force acting on a steel sphere submerged in water! This demonstration covers the physics behind buoyant force, free body diagrams, and Newton’s Third Law. We'll use measurements and calculations to show...

Master Newton’s law of universal gravitation through intuitive explanations, real-world examples, and full vector analysis. Learn how to calculate gravitational force, understand the inverse square law, and apply Newton’s third law in...

Understand the concept of apparent weight in an elevator using Newton’s Second Law and free body diagrams. Learn how your weight changes when the lift accelerates, decelerates, or goes into free fall.

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...

Calculate the altitude of a satellite in geostationary orbit which is an orbit with the same 24 hour period as the Earth and always located directly over the same location on the equator. Geostationary orbit is a special case of...

Isaac Newton's Laws of Motion explain how and why objects move as they do - the principles which underlie all of modern mechanics. Physics - Forces - Learning Points. Sir Isaac Newton published his laws of motion in 1687. Every movement...

The video is a lecture or presentation on forces and work. The speaker defines what work is and provides examples of how energy is transferred from one form to another. The speaker also explains how to measure work and the equation for...

In this video Paul Andersen explains why astronauts are weightless. He also explains how Newton's Universal Law of Gravitation can be used to calculate the gravitational force between objects.

SUMMARY

"Facts" that are not quite correct: 1) There is no gravity in space 2) Nothing can go faster than the speed of light. 3) Bees shouldn’t be able to fly according to physics. I will explain this using Physics 4)...

Delve into the world of physics with our latest video on buoyant force! Join us as we explore the concept of buoyant force acting on objects floating on fluids. Learn how to calculate the percentage of a floating object submerged in a...

The results are in – gravity is weaker than it should be! Lotus is certain that someone is digging a giant cave underneath the Big Apple, but Mark isn’t convinced. Who do you think is correct? This lesson will assess the accuracy,...

This is a collection video on gravity, which explains the relationship between gravity, weight, and mass. The video defines gravity as a phenomenon causing attraction between all masses and shows how it affects different objects...

Gravity is mysterious, isn't it? If all matter exerts gravity, why don't we all just drift towards each other all the time? Well, as you know, it depends on the masses of the two objects and the distance between them. Your friend says...

Discover the fascinating world of physics with our latest video on buoyant force! Join us as we conduct an experiment demonstrating the concept of buoyant force and the weight of the fluid displaced by an object. Learn how to calculate...

This is a lecture video on Newton's third law that discusses the forces that act between two interacting objects. The speaker provides several examples, including a man sitting on a chair, a cannon firing a cannonball, a fish swimming...
