Question
In your frame of reference, your body is of course at rest. However I observe your body to be travelling at constant velocity of 5 m/s. Is my reference frame an inertial frame? You are in a closed box, with no windows. The only object in the box with you is a scale. A) On the scale, you measure of a force of 68.0 N. Are you in an inertial reference frame? B) OK, you are upgrade to a box with a window. The box is now loaded into an airplane, which drops you from 15,000 m. As you fall, the scale records no force at all. Are you now in an inertial reference frame? C) A parachute deploys, which lowers you gently to the surface of the earth. Now are you in an inertial reference frame? D) Why?Explanation / Answer
4) body is moving with constant velocity(no acceleration) wrt other frame.
and body was at rest so inertial.
hence my reference frame will also be inertial.
5) (A) force 68 N is very less than compared to the weight of person.
that means frame is accelerating in downward direction.
so this is non-inertial frame.
(B) now frame is accelerating with downward acc of g.
hence non-inertial frame.
(C) at near the surface of earth,
parachute moves with constant velocity.
hence inertial frame.
(D) I have given all the reasons with the answers.
