don’t realize is that Football is almost entirely a game of physics‚ angles‚ and probability with only a bit of strength. The sport may seem to be about tackling people and about making those amazing one handed catches but if you understand a couple of topics like Newton’s laws of physics‚ angles‚ speed‚ and acceleration you could be just as good as Tom Brady‚

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic

Measurement of the distance‚ the thickness and the radius of curvature Purpose : To learn how to use vernier caliper‚ micrometer and spherometer to measure internal and external diameters of a pipe‚the thickness of a copper rods‚ and the radius of curvature of spherical lenses. 1) Vernier caliper: As shown in Fig. 1 the main fixed scale in the vernier caliper has 1 mm gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called

A superconductor is a metallic alloy that conducts electricity without resistance‚ below a certain temperature. Once in motion‚ an electrical current will flow in a closed loop within a superconducting material. This is the closest to scientists of a perpetual motion machine. In 1911‚ Heike Kamerlingh Onnes first observed superconductivity. He used mercury and cooled to four degrees Kelvin. When the mercury reached that temperature‚ the resistance disappeared. That meant that the electrical current

Flight is a phenomenon that has long been a part of the natural world. Birds fly not only by flapping their wings‚ but by gliding with their wings outstretched for long distances. Smoke‚ which is composed of tiny particles‚ can rise thousands of feet into the air. Both these types of flight are possible because of the principles of physical science. Likewise‚ man-made aircraft rely on these principles to overcome the force of gravity and achieve flight. Lighter-than-air craft‚ such as the hot

A catapult is an ancient device used to launch heavy objects at targets during war. The catapult dates all the way back to 400 be when it was invented in the Greek town of Syracus. The main types of catapults are trebuchet‚ mangonel‚ onager and ballista. There are many more types of catapults also. Catapults were an absolute revelation in weaponry. The mangonel was best suited for launching projectiles at lower angles to the horizontal‚ which was useful for destroying walls‚ as opposed to the
