Question

Why is the mechanical advantage of using a single pulley always 1? Assume there’s no friction.
A. The input force is in a different direction than the output force.
B. The input force is less than the output force.
C. The input force is greater than the output force.
D. The input force is equal to the output force.

Answer 1

Answer:

❥In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity
