Kinetic and potential energy are defined as combinations of more basic quantities: position, velocity and mass. These combinations are chosen so that their sum is conserved. It’s actually remarkable that there’s any such combination of...

Bumblebees fly, lights turn on, and you can ride a bike without falling over. We all know these things to be true, but what you may not know is the real reason behind why they work. Join Olivia to bust seven myths about motion.

The size, shape, and designs of the balls used in sports are usually the results of decades or even centuries of trial and error, and the cute, dimply li'l golf ball is no different!

What is a differential equation, the pendulum equation, and some basic numerical methods

Energy is the most powerful and useful concept in all of physics, but what exactly is it?

High-pitched falsetto singing can show off a singer’s physical ability, because singing this way takes a lot of effort and some careful physics!

Mr. Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems.

Maybe you'd like to just hear about one topic for a while. We understand. So today, let's just watch some videos about Gravity. We'll learn about why we don't fly off into space, what mass has to do with it, how does air resistance work,...

Air resistance! It's a thing! In this episode of Crash Course Kids, Sabrina does her own Astronaut Experiment to show us how we can prove it!

In this video Paul Andersen explains how free-body diagrams can be used to solve kinematics problems. The only two parts of a free-body diagram are the object and all external forces acting on the object. Numerous situations are...

So, what would happen if you dropped a hammer and a feather at the same time, from the same height? Well, the hammer would hit the ground first, right? But why? You might think it's because the hammer is heavier, or has more mass than...

The size, shape, and designs of the balls used in sports are usually the results of decades or even centuries of trial and error, and the cute, dimply li'l golf ball is no different!

Bumblebees fly, lights turn on, and you can ride a bike without falling over. We all know these things to be true, but what you may not know is the real reason behind why they work. Join Olivia to bust seven myths about motion.

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.

What is a differential equation, the pendulum equation, and some basic numerical methods

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.

Howcast - Learn how to demonstrate mass, shape, and air resistance for a science project with the instructions in this Howcast video.

Pupil outcome: I can carry out an investigation into air resistance and evaluate results. Key learning points: - Scientists often repeat tests in order to gather more information and make sure their results did not happen by chance. -...

Forces are all around us and are the reason why objects accelerate (speed up, slow down or change direction)! Forces can either be balanced or unbalanced. When the forces are balanced, the net force is 0 and the object's motion will not...

If you’re trapped high up in a deadly predicament with only a great fall as a means of escape, should you take your chances with fall damage?

Vincent teams up with world parachuting champion Julien Degen to replicate a skydiving stunt from action films. By jumping from over 4,000 meters, they measure how different body positions affect falling speed. Discover the surprising...

Vincent and parachuting champion Julien Degen take on the challenge of catching someone mid-air, as seen in James Bond and Largo Winch films. By jumping in different positions, they test if a parachutist can catch another who jumped...

The video discusses a 2014 U.S. Physics Team exam question about the shape of a cable hanging from a helicopter flying horizontally. The experiment showed that when flying at a constant speed, the rope hangs diagonally to the left due to...

The world's largest rainfall simulator, located in Sucuba, Japan, is a vital research facility used to study and prevent natural disasters caused by heavy rainfall, such as flooding and landslides. With 550 nozzles, it can simulate...
