Center of Gravity The point in a body or system of bodies at which the whole mass may be considered as concentrated. When an object’s weight is distributed uniformly‚ the center of gravity lies at its geometrical center. For irregular shaped objects‚ the center of gravity is near to the concentration of its mass. Equation: Where: X= center of gravity xi= distance of the objects from fulcrum or arbitrary axis mi= mass of the object Sample Problems 1.) Suppose your lab partner has

What is the direction of the acceleration vector for each of these situations? Remember that if an object speeds up‚ then the velocity and acceleration vectors are in the same direction. If an object slows down‚ then they are in opposite directions. Any object that is traveling in a vertical direction also experiences acceleration due to gravity. Left: Object travels to left and speeds up. Down: Object is tossed upward. A ball is tossed up into the air with a velocity of 50 m/s. The figure

Anti-gravity is the idea of creating a place or object that is free from the force of gravity. It does not refer to the lack of weight under gravity experienced in free fall or orbit‚ or to balancing the force of gravity with some other force‚ such as electromagnetism or aerodynamic lift. Anti-gravity is a recurring concept in science fiction. In Newton’s law of universal gravitation‚ gravity was an external force transmitted by unknown means. Under general relativity‚ anti-gravity is impossible

Duncan‚ Vinny‚ and Wayne are all friends working - or wasting time - the summer before senior year in high school. Duncan is the soul‚ Vinny the brains‚ and Wayne the muscle. At the end of the previous summer‚ Duncan tried to save a drowning girl and failed. Not being a hero has really affected his life‚ particularly his relationship with his girlfriend Kim. Also‚ he is now terrified of swimming‚ especially when the nightmares come back. Duncan’s summer job is with the public transit lost and

and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus and a computer simulation will show you some effects of changing the proportions
