maintain a constant radius of uniform circular motion while ensuring that all of the centripetal force is provided by the clamp and measured on the spring scale. Practice whirling the stopper in a horizontal plane until you can keep the paper clip a short distance just below the bottom of the tube. If the paper clip touches the bottom of the tube‚ then the clamp is no longer supplying the centripetal force. If the paper clips rises or falls appreciably as the stopper whirls then the radius of the

3. Recent technological developments have allowed greater use of the electromagnetic spectrum 1. describe electromagnetic waves in terms of their speed in space and their lack of requirement of a medium for propagation In space (a vacuum) electromagnetic waves travel at the speed of light‚ a constant equal to 3.00108ms1. Unlike sound waves‚ electromagnetic waves do not vibrate particles‚ therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

He proposed that objects in motion did not come to a stop because of a non-existent force‚ but because of a force between a surface and an object. This concept would later help further develop Newton’s Laws of Motion. 4.
