A weight machine _____.
A.decreases the amount of input force required
B.increases the input distance
C.changes the direction of the input force
D.reduces the amount of input work
i think it is C please help me
its A fairly certain
Im so stuck on this one quiz on connexus ans its about to drive me crazy bro
i cant do this anymoreee can someone please help me before my head explodes
i think its A i HOPE
To determine the correct answer, let's analyze the options one by one:
A. Decreases the amount of input force required: This option implies that a weight machine somehow makes it easier to apply force. However, weight machines actually require the same amount of force as without them, so this option is incorrect.
B. Increases the input distance: This option suggests that a weight machine somehow increases the distance you have to move an object. However, weight machines do not affect the distance you need to move an object, so this option is also incorrect.
C. Changes the direction of the input force: This option describes a common feature of weight machines. Weight machines use pulleys, levers, or other mechanisms to change the direction of the force applied, allowing you to lift weights in a more convenient way. This option is correct.
D. Reduces the amount of input work: This option implies that weight machines somehow make it easier to do work. However, weight machines do not reduce the amount of work required to lift an object; they only change the way the work is done. So, this option is incorrect.
Therefore, the correct answer is indeed C. A weight machine changes the direction of the input force.
