Consider a bead starting at rest at Point B. It then slides along the frictionless wire to M. KE refers to the kinetic energy of the bead. PE refers to the gravitational potential energy of the bead. Total Energy refers to the total mechanical energy of the bead. Tell whether each of the following is greater than, equal to, or less than. 1. The Total Energy of the bead at Point B is the TE at H.
2. The KE of the bead at Point K is the KE at G.
3. The PE of the bead at Point M is the PE at B.
4. The KE of the bead at Point M is the KE of the bead at Point F.
