Question

Which one of the following systems would constitute aninertial reference frame?

a. a rocket undergoing uniformacceleration
b. a weather balloon descending atconstant velocity
c. a train rounding a turn at constantspeed
d. an orbiting spacestation
e. a rotating merry-go-round Which one of the following systems would constitute aninertial reference frame? a rocket undergoing uniformacceleration a weather balloon descending atconstant velocity a train rounding a turn at constantspeed an orbiting spacestation a rotating merry-go-round

Explanation / Answer

        Aninertial frame of reference has a constant velocity. That is, it ismoving at a constant speed in a straight line, or it is standingstill. Understand that when something is standing still, it has aconstant velocity. Its velocity is constantly zero meters persecond.

          To say that the velocity of a frame of reference is constant isthe same as saying that the frame is not accelerating. So, we coulddefine an inertial frame of reference to be a coordinate systemwhich is not accelerating. Hence    b.                        a weather balloon descending at constant velocity   wouldconstitute an inertial reference frame. Hope this helps u! Hence    b.                        a weather balloon descending at constant velocity   wouldconstitute an inertial reference frame. Hope this helps u! Hope this helps u!
