ESS 101 B LAB 5 EXAM REVIEW UPDATED
COMPLETE QUESTIONS AND ANSWERS
GRADED A+
◉ What type of energies should be considered in pendulum motion?
Answer: Kinetic and gravitational potential energy.
◉ What values can the kinetic energy of the pendulum take? Answer:
It can take any positive value.
◉ When is the maximum potential energy of the pendulum observed?
Answer: At the highest points of the swing.
◉ The motion of the pendulum can be started by giving it an initial
push, and thus an initial speed at the equilibrium point (the lowest
point). What is the effect of increasing this initial speed on the
maximum elevation reached? Answer: The maximum elevation is
greater. At the maximum height the larger kinetic energy has been
fully converted into a larger potential energy and thus into a greater
elevation.
