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 goal for a complete shake off Theory          When the pendulum is at the apportion of its swing it is momentarily stationary. It has nix energising energy and level best gravitational potence energy. As the pendulum falls the potential energy is transferred to kinetic energy. The speed increases as the pendulum falls and reaches a uttermost at the bottom of the swing. here the speed and kinetic energy ar 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 zip fastener as it reaches the top of its swing, with the potential energy a maximum again. A small count of energy is lost callable to air resistance as the pendulum swings. This means each swing is slightly smaller than the star before. There be 2 soldierys acting on the pendulum dock. Gravity tries to twisting the give chase downward but this is resisted by the tension in the string. As in that location 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 by the middle of the swing.

force due to gravity = cargo of bob = mg m = mass of bob g = gravitational fi eld strength g = 10 N/kg at the Earths surfa! ce 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, measuring research laboratory procedures should be undertaken such as footware. If you extremity to get a full essay, order it on our website: OrderCustomPaper.com
