So, if gravity pulls everything down, then why don't things on the bottom of the Earth get pulled down into space? In this episode of Crash Course Kids, Sabrina talks about gravity and explains that when we talk about gravity pulling...

Mr. Andersen explains the importance of physics as a science. History and virtual examples are used to give the discipline context.

Why would it be hard to pedal a 10,000 pound bicycle? This simple explanation shows how Newton's 3 laws of motion might help you ride your bike.

I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of...

Mr. Andersen defines Newton's three laws of motion. He describes how the first law relates to inertia, how the second law relates to mass and acceleration, and how the third law allows a rocket to launch.

New ReviewNewton’s Third Law forces are always equal and opposite, but they act on different objects. Learn how to identify these force pairs and draw the correct free-body diagrams.

New ReviewEn este video te explicaremos cuál es la tercera ley de Newton, acción y reacción, te daremos ejemplos de la tercera ley de Newton y cómo interactúan la acción y la reacción. Siempre que realices una acción sobre un cuerpo, este va a...

New ReviewEn este video te explicamos qué son las leyes de Newton o las leyes del movimiento de Newton, cuáles son las leyes de Newton, qué es movimiento, qué es fuerza y qué es aceleración. Las leyes de Newton o leyes del movimiento de Newton,...

New ReviewEn este video te explicaremos cuál es primera ley de Newton o la ley de la inercia, ejemplos de la primera ley de Newton, qué es fricción y qué es gravedad. La primera ley de Newton dice que cualquier objeto que está quieto o en...

See Newton's third law in action as we explore buoyant force using a steel sphere, water, and a digital scale. Watch how submerging the sphere changes the readings, and discover why the scale reading matches the buoyant force. Perfect...

This video provides an introduction to Newton's three laws of motion, explaining how they help us understand the movement of objects in our everyday lives. It discusses the first law of inertia, which states that an object remains still...

This video discusses Newton's first law of motion, also known as the law of inertia. It explains how Newton built upon the experiments of Galileo to formulate this law. The video illustrates the concept using the example of a ball on the...

This video explains Newton's Second Law of Motion, which states that the amount of force applied to an object affects its speed. Using relatable examples such as Tony pushing a car and a bicycle, as well as pushing empty and full...

This video provides an explanation and examples of Newton's third law of motion, also known as the law of action and reaction. The law states that for every action, there is an equal and opposite reaction. The video illustrates this...

Pupil outcome: I can investigate and calculate the size of turning forces. Key learning points: - A moment causes turning. - Moment = force × (perpendicular) distance from the pivot. - Moments are measured in Newton-metres (Nm).

This content defines angular momentum (ℓ) for a particle as the cross product of its position vector (r) and linear momentum (p), i.e., ℓ=r×p=m(r×v). It clarifies that angular momentum is a vector quantity defined with respect to a...

Finally understand Newton's Laws with clear, step-by-step explanations and simple calculations! This comprehensive guide breaks down all three laws of motion in a way that actually makes sense. You'll learn how to solve force and...

After a number of tutorials covering first-order differential equations, it's time to start tackling second-order differential equations. These contain a second derivative term, and they are quite useful in physics. To introduce these,...

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...

Newton's 2nd Law of Motion tells us that if a net force is applied to an object then that object will accelerate in the direction of the net force. This means that is a force a force is applied to an object, it will either speed up, slow...
