Question

Consider a bead starting at rest point L. 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.

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.

Explanation / Answer

(1) Since the wire is frictionless hence there wont be any loss in energy therefore total energy at B is equal to total energy at H

EQUAL TO

(2) Since point K is at higher than point G hence potenial at point K will be high than potential at point G which menas KE at K will be less than KE at G

LESS THAN

(3) Since point B is at higher than point M hence potenial at point B will be high than potential at point M

LESS THAN

(4) Since M and F are at same height hence they have same PE which means same KE hence

EQUAL TO
