MCAT Question of the Day


  • Q:

    An elevator is descending down an elevator shaft with constant speed. The elevator is supported by a single cable. Assuming the only forces at play are the tension in the cable and the force of gravity, then:

     

    A

    the magnitude of the work done by the tension force is larger than the magnitude of the work done by gravity.

    B

    the magnitude of the work done by the tension force is smaller than the magnitude of the work done by gravity.

    C

    the net work done by the two forces is zero.

    D

    the work done by the tension force is zero.
