Question

It is easier to draw up a wooden block along an inclined plane than to haul it vertically, principally because:

• A. the friction is reduced
• B. the mass becomes smaller
• C. only a part of the weight has to be overcome
• D. $g$ becomes smaller

Answer 1

The correct option is C only a part of the weight has to be overcome

The vertical plane $W=mgh$
for inclined plane $W^{\prime }=mghsin\left(Q\right)$
$sinQ<1$
$W>W^{\prime }$
hence only one part of weight is to overcome
