Measure the mechanical efficiency of an inclined plane lab report

Physics experiment specific steps and requirements 1, the mechanical efficiency of the research page and what is the relationship between its degree of inclination? Conjecture: the greater the inclination of the inclined plane, the greater the mechanical efficiency of the design of the experiment: equipment: the inclined plane, wooden block, spring dynamometer, scale (the experimental process, to keep the weight of the wooden block of the same G, the length of the inclined plane S is unchanged, changing the height of the inclined plane h and the pulling force F) Experiment: (fill in the table below the measured data) ① with a spring dynamometer to determine the gravitational force of the wooden block of the G ② the length of the inclined plane with the scale of the two places S and height h1 ③ Use a spring loaded dynamometer to pull the block in a uniform linear motion and read the tension F1 ④ Change the inclination of the inclined plane and measure the height of the inclined plane h2 ⑤ Use a spring loaded dynamometer to pull the block in a uniform linear motion and read the tension F2 Table 1 Inclination of the Inclined Plane Weight of the Object G/N Height of the Inclined Plane h/m Tensile Force along the Inclined Plane F/N Length of the Inclined Plane s/m Useful Work W Yau / J Total Work W Total / J Mechanical Efficiency Slower Steeper Calculation formula: W have 1 = G h1 W have 2 = G h2 W total 1 = F1S W total 2 = F2 S Conclusion: the greater the inclination of the inclined plane, the higher the mechanical efficiency
