P1 What is the potential energy of the bob in terms of the string length (L), the mass of the bob (m), and g? Take the zero of potential energy to be at the bottom of the bob’s path.
P2 What is the kinetic energy of the bob in terms of the sting length L, the tension in the string when the bob is at the bottom of its arc (Ttotal), the mass of the bob (m), and g?
P3 Suppose now that the force probe is calibrated so that when
the mass hangs motionless, the force probe reads zero tension. What
is the KE of the bob in terms of the sting length L, the calibrated
tension T, the mass of the bob (m), and g?
