A tight rope walker is able to maintain balance, based on the location of the center of mass above the rope. Stability is improved by the tight rope walker carrying a long pole. The principle behind this concept is in the idea that; with the long pole being flexible the walker can easily swing in either side to maintain a balance. The longer the pole the lower the rate of angular rotation, this therefore allows the walker to re-adjust to balancing state when he begins to lose balance. Contrary to the case of short pole or just bear arms ( Continue reading...

Experiment 4: Projectile Motion
Projectile motion is a special type of motion involves two components of motion – horizontal and vertical. But motions in two directions are independent of each other. Flight of ball is an example of projectile motion. This two dimensional motion can be determined as two linear motions in two mutually perpendicular directions –one along horizontal direction and the other one along vertical direction. Projectile motion can be analyzed with the help of equations of motion. Vector equations and vector rules are generally used as the motion occurs in two dimensions. Gravity force has primary importance in projectile motion. Effect Continue reading...

Example Of Essay On Gravity
Gravity is precisely defined as a pulling force; it pulls objects (matter) towards it. The intensity of force is directly proportional to the quantity of matter, so the things composed of more matter tend to be pulled with greater intensity of force. The mass of any object is the fundamental unit being used to measure the quantity of matter it that object. Therefore, the more heavy and matter in the object is, the higher gravitational pull will it put forth. Earth exerts a pulling force on the objects (Human beings) that move on its surface and as a result Continue reading...
