FIGURE 8-2  A mass is attached to one end of a string. The other end of the string is attached to a rigid support. The mass is released at A and swings in a vertical arc to points B, C, and D.
-Refer to Fig. 8-2. At what point does the mass have the most kinetic energy?

Quizplus · Accepted Answer

The mass has the most kinetic energy at the lowest point in its path, which is typically point C in a pendulum or similar system, as potential energy is converted to kinetic energy.
