Question
2. A student is comparing the results of trial I to trial 2 (in which the same glider is used with different angles of inclination) and makes the following statement: The work is greater for the steeper slope because the glider travels a greater distance in that case, and gravity is still pulling it down. The same force times the greater distance means more work. a. Do your results agree with the results the student is describing? b. Do you agree with the reasoning used by the student in interpreting his results? If so, explain why you agree. If not, identify the error (or errors) in the students? reasoning. 3. A student is making a prediction regarding the results of trial 2 to trial 3 (in which different gliders are used with the same angle of inclination) and makes the following statement: The final speed of the short glider will be less than that of the long glider because the short glider has less moss and therefore less gravitational force acting on it. So the short glider will hove less acceleration, and therefore go more slowly at the bottom of the incline. a. Do your data support this student?s prediction? If not, describe the way in which your results differ from this prediction. b. The student?s reasoning is incorrect. Explain why, and give a correct explanation for your results.Explanation / Answer
2) work done by the conservative force depends on the intial anf final conditions
it does not depends on the path travelled by the body. so in both the conditions work must be same
3) if potential energy is small the kinetic energy is large
for both the bodies total mechanical energy is same
short glider has less potential energy and large kinetic energy
similarlly
long glider has max potential energy and small kinetic energy
