TED-ED: How your muscular system works - Emma Bryce
Each time you take a step, 200 muscles work in unison to lift your foot, propel it forward, and set it down. It's just one of the many thousands of tasks performed by the muscular system: this network of over 650 muscles covers the body...

Temperature
In this video Paul Andersen explains how the temperature is a measure of the average kinetic energy of particles in an object. The temperature is proportional to the average kinetic energy according to the Kelvin scale. At absolute zero...

Motion
In this video Paul Andersen describes motion as the movement of an object over time. Displacement, velocity and acceleration are all defined. An experiment in motion is used to calculate velocity and acceleration of a tennis ball.

Rotational Motion
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...

Did We Find Longitude Thanks To A...Clock?
The equator is a clear and accurate line around Earth that makes measuring latitude a precise science, but when it came to figuring out how to do that with longitude, British sailors were at a loss. Until they devised a competition.

Kinetic and Potential Energy
In this video Paul Andersen explains how the energy in a closed system can be converted from kinetic to potential to kinetic energy. Sample problems and a simulation is contained.

Special Relativity: Crash Course Physics
So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion? In this episode of Crash Course Physics, Shini talks to us about perspective, observation, and how relativity is REALLY weird!

Newton and Leibniz: Crash Course History of Science
The standard story of the Scientific Revolution culminates with the long life of one man: Sir Isaac Newton—a humble servant of the Royal Mint, two-time parliamentarian, and a scientific titan whose name, along with Einstein’s, is...

PS2C - Stability and Instability in Physical Systems
Paul Andersen explains how physical systems remain stable and unstable over time. The sum total of interactions acting on the system determine its stability. Feedback loops are used to maintain stability but require energy. If the energy...

TED-Ed: What can Schrodinger's cat teach us about quantum mechanics? - Josh Samani
The classical physics that we encounter in our everyday, macroscopic world is very different from the quantum physics that governs systems on a much smaller scale (like atoms). One great example of quantum physics' weirdness can be shown...

Forces
Forces are pushes or pulls on an object. Forces can be determined by measuring the motion of an object. If an object accelerates then a force is present.

PS1B - Chemical Reactions
In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed. He explains the difference between changes in state and changes in molecules. He discussed collision theory and explains why...

Work and Power
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 the...

PS2A - Forces and Motion
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...
