A bike is hanging from a hook in a garage. Consider the following forces.
(a) The force of the Earth pulling down on the bike.
(b) The force of the bike pulling up on the Earth.
(c) The force of the hook pulling up on the bike.
(d) The force of the hook pulling down on the ceiling.

Which two forces are equal and opposite because of Newton's third law?


Which two forces are equal and opposite because of Newton's first law?

    Do you have any thinking on this? the question is well stated.

  • physics -

    for Newton's third law: i believe it would be the force of the hook on the bike and force of the bike pulling on the earth
    and for second law:force of earth pulling down on bike and force of hook pulling down on ceiling..but im not too sure?
