Question

Consider a bead starting at rest point B. It then slides along the frictionless wire to E. 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.

1) The KE of the bead at Point D is _____ the KE of the bead at Point K.

2) The Total Energy of the bead at Point J is _____ the TE at G.

3) The KE of the bead at Point C is _____ the KE at A.

4) The PE of the bead at Point C is _____ the PE at A.

Explanation / Answer

we have total enrgy will always be conserved

so

1).equal

2).equal

3).greater

4).less
