Flying kites is a popular hobby in Malaysia and very much part of the culture. With fun animations, this lesson looks at kite flying science to introduce basic ideas related to the dynamics of kite flying.
What is circular motion, and how does it work? Learn the math behind it!
This video includes an introduction to the concept of the vector, a brief review of vector properties, an exploration of vector properties using physical intuition based on displacements, and more.
The objective of this lesson is to illustrate how a common everyday experience (such as playing pool) can often provide a learning moment.
A computer simulation of the molecular stucture of a metal alloy, showing the boundaries between microcystalline grains (white lines forming hexagons), shows a small crack (dark horizontal bar just right of bottom center) that mends itself as the metal is put under stress. This simulation was ...
Researchers at MIT explain what exactly an exoplanet or extrasolar planet is, why we study them, and how they can be detected.
A double cone is placed on the bars of an inclined plane. Instead of rolling down the plane the cone rolls up. Although the plane slants upward, the bars diverge so that the rotational axis of the cone, which passes through the center of mass, actually moves downward.
A 100uF capacitor is charged to 3kV (450 joules) and then discharged through a thin iron wire, causing it to explode.
A small amount of water is placed inside an airtight copper tube, with the end sealed by a rubber stopper. The tube is heated using a blowtorch, causing the water inside to boil. As the water changes from a liquid to a gas the pressure inside the tube increases. Eventually the pressure blows ...
This computer simulation shows a cross-section of the plasma inside a tokamak reactor. In this simulation, only the large-scale turbulence effects are modeled — which is adequate for some cases

Why is the ant mightier than an elephant?
A DC current is sent around a wire loop that is free to rotate. The current causes the loop to feel a torque in the presence of a magnetic field. Switching the current when the loop flips over allows it to continue accelerating, demonstrating the principle of a DC motor and the Lorentz force ...
Can something be a solid and a liquid at the same time?
“Gravity assist” is a maneuver performed by interplanetary spacecraft to travel farther on less fuel.
Does gravity affect everything at the same rate? An experiment to explain gravity.
What makes the Moon orbit the Earth and how can it be calculated?
