Work and Energy Theorem

Work and Energy Theorem Kevin Objective: The objective of this experiment is to investigate what work is, and how it relates to energy. We will learn different forms of energy and how energy is used to determine the relationships between work and energy. Data and Calculations: Part A: Work Done by a Constant Force Mass of Weight 199.8 g Starting Time 1.80 sec Starting Position 0.006 m Ending Time 5.00 sec Ending Position 0.215 m Average Force 2.017 N Integral 0.3152 mN ?U = mg?h ?U = (0.1998kg)(9.81m/s2)(0.215m ? 0.006m) ?U = 0.4096 Nm The average work is the average force multiplied by ?h. Wave = (2.017 N) (0.215m ? 0.006m) Wave = 0.4216 The percent difference between the calculated ?U value and the average work is
