To investigate how the length of a simple pendulum affects the time for a complete swing

Aim          To investigate how the length of a simple pendulum affects the current for a complete thrill Theory          When the pendulum is at the fall into place of its swing it is momentarily stationary. It has nix energising energy and level best gravitative potence energy. As the pendulum falls the potential energy is transferred to energising energy. The speed increases as the pendulum falls and reaches a maximal at the bottom of the swing. here the speed and kinetic energy argon a maximum, and the potential energy is a minimum. As the pendulum rises the kinetic energy is transferred defend to potential energy. The speed of the pendulum decreases and falls to set as it reaches the top of its swing, with the potential energy a maximum again. A small count of energy is lost repayable to air resistance as the pendulum swings. This means each swing is slightly smaller than the star before. There atomic number 18 cardinal ram downs a cting on the pendulum wharfsleigh. Gravity tries to twisting the bob downwards but this is resisted by the tension in the string. As in that respect be only two forces they discharge only be balanced when they are in foe directions. This only occurs when the pendulum is in the middle of its swing, so for the rest of the time the two forces are unbalanced; hence the bob swings sand and forth. The two forces are equal and opposite. This means there is no resultant force on the bob. It could either be stationary, or passing through and through the middle of the swing.

force due to gravity = cargo of bob = mg m = mass of bob g = gravitational field str! ength g = 10 N/kg at the Earths surface The two forces are not in opposite directions. This means there is a resultant... May i allude that for your risk assessment, the risks involved would be the possibility that the bob could be unintentionally dropped or swung to hit another person. Also, touchstone research laboratory procedures should be undertaken such as footware. If you pauperization to get a full essay, order it on our website: OrderCustomPaper.com
