Introduction: The study of the ballistic pendulum began with Benjamin Robins in the early 1700 ’s. Robins was an English mathematician and writer on ballistics‚ and used this testing apparatus for the evaluation of the strength of gunpowder and the measurement of air resistance (Calvert‚ 2006). At the time of the American Revolution a loyalist named Benjamin Thompson also utilized and expanded the use to the ballistic pendulum. He further evaluated the efficiency of gunpowder. He fired from

.:First experiment:. .Problem: How will the length of a pendulum affect the amount of swings per minute? .Hypothesis: I believe that the length of the pendulum will affect the amount of swings per minute because when the string is shorter in length‚ there would be less friction between the string and the atmosphere‚ causing the string to go faster. .Materials: * String ( should be 70-90 cm long) * Metal washers * Stopwatch * Metric ruler * Stand * Extra washers (You will

Method/Pendulum Exercise Worksheet 1. What is the difference between an observation and an inference? Observations are based on collecting knowledge through our senses. An inference is making an educated guess based on observation. 2. In doing science‚ why are hypotheses either supported or not supported‚ but never proved beyond all doubt? There are many other factors that could be unknown and new data could be found in the future to support or not support a hypothesis. 3. For this pendulum exercise

Pit Bulls are commonly recognized as wild‚ vicious and inherently dangerous animals‚ which is false. “Singling out a particular breed or type of dog has repeatedly been proven to be ineffective because breed alone is not predictive of whether a dog may pose a danger” (The HSUS). How can you look at any given dog or certain breed of dog and know whether it is dangerous‚ just by the way it looks? The answer to that question is‚ you can’t. Look at it this way‚ as a similar scenario‚ how do you know
