An object at the surface of the Earth (thus, a distance R from the center of the Earth)
weighs 160 N. Its weight at a distance 4R
from the center of the Earth is:
1. 10 N
2. 2560 N
3. 640 N
4. 160 N
5. 40 N

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

Answerit increases at a steady rate;
