Question

station 4
simple machines
which inclined plane would require the least amount of force to move the box?
j. inclined plane a
k. inclined plane b
l. inclined plane c
m. the amount of force applied would be the same for all.

Explanation:

Step1: Recall force - distance relationship

The force required to move an object up an inclined plane is related to the length and height of the plane. The longer the inclined plane for the same height, the less force is required.

Step2: Compare the lengths of the inclined planes

Among A, B, and C, inclined - plane B is the longest for the same height (the vertical height that the box needs to be lifted is the same for all three).

Answer:

K. inclined plane B
