Newton's second law of motion:
A. Explains the relationship between forces on two mutually effective objects
B. Also known by the law of inertia
C. It is helpful to understand the effects of force
D. Also known by the law of conservation of energy
A. centrifugal force
B. inertia
C. centripetal force
D. gravitational force

option should be D. Uniform motion (up or down) = no change in apparent weight
Accelerated motion (up or down) = change in apparent weight
