MCAT Question of the Day


  • Q:

    Objects have a terminal velocity due to air resistance but do not have a similar terminal velocity due to friction when sliding across surfaces. This is because:

     

    A

    objects sliding down inclines are completely subject to the force of gravity while objects falling through the air are not.

    B

    air resistance is proportional to velocity while kinetic friction is irrespective of velocity.

    C

    kinetic friction is weaker than static friction.

    D

    objects attached to surfaces are not subject to air resistance.
