Arock is suspended from a string; and it accelerates downward. which one of the following statements concerning the tension in the string is true?
a) the tension points downward.
b) the tension is less than the weight of the rock.
c) the tension is equal to the weight of the rock.
d) the tension is greater than the weight of the rock. the tension is independent of the magnitude of the rock's acceleration.
Answers: 1
= tension force in the string in upward direction
= Force of gravity on the rock in down direction
= mass of the rock 
= acceleration of the rock
