Consider the simple pendulum in the figure. The pendulum is released at point A, swings through its lowest point at point C, and reaches its turning point at point D. If we include the effects of air resistance, which of the following statements must be true? (There may be more than one correct answer.)

Transcribed Image Text:Consider the simple pendulum in the figure. The pendulum is released at point A, swings through its lowest
point at point C, and reaches its turning point at point D. If we include the effects of air resistance, which of
the following statements must be true? (There may be more than one correct answer.)
The work done by the tension force is zero at all points along the pendulum's
motion
The work done by air resistance is negative at all points along the pendulum's
motion
The gravitational potential energy of the pendulum at point A is equal to the
gravitational potential energy at point D
The work done by the gravitational force is positive at all points along the
pendulum's motion
