Gravity Review Question 37 Question 19 of 39 When you ride a fast elevator upward, you feel slightly heavier as the trip begins and slightly lighter as the trip ends. How is this phenomenon related to the equivalence principle? a. When the elevator begins to move, its hoisting mechanism exerts an upward force upon you, so you feel heavier. When the trip ends, the direction of the force is downward so you feel lighter. b. When the elevator begins to move up, you feel an increase in your apparent weight. You cannot tell the difference between increased apparent weight due to acceleration and increased weight due to increased gravity. Oc. The elevator moves with acceleration when it begins and stops moving, so it is not an inertial frame at that time and you can say where this acceleration is directed. Od. When the elevator begins to move, your speed and that of the elevator compartment increase and you feel an increase in your relativistic mass. When the elevator stops, the speed decreases and so the relativistic mass decreases.

When you ride a fast elevator upward, you feel slightly heavier as the trip begins and slightly lighter as the trip ends. How is this phenomenon related to the equivalence principle?
O a. When the elevator begins to move, its hoisting mechanism exerts an upward force upon you, so you feel heavier. When the trip ends, the direction of the force is downward so you feel lighter.
O
b. When the elevator begins to move up, you feel an increase in your apparent weight. You cannot tell the difference between increased apparent weight due to acceleration and increased weight due to increased
gravity.
Oc. The elevator moves with acceleration when it begins and stops moving, so it is not an inertial frame at that time and you can say where this acceleration is directed.
Od. When the elevator begins to move, your speed and that of the elevator compartment increase and you feel an increase in your relativistic mass. When the elevator stops, the speed decreases and so the
relativistic mass decreases.

a. Newton's third law of motion, because our forces occurred in a pair directed in opposite directions.
Ob. Newton's law of universal gravitation because my friend's forearm was pulled to the table by the gravitational force.
O
Oc. Newton's second law of motion applies because the force that I applied to the mass of my friend's arm was sufficient to accelerate it to the table.
O
d. Newton's first law of motion because my friend stopped exerting the force and his forearm moved uniformly in a straight line.

A
You weigh
100 pounds, your friend weighs
200 pounds, and you are in an arm wrestling contest with each other. Now in one swift motion you plant your friend's forearm on the table, winning the contest. Which of Newton's laws applies to
this motion and why?
