The friction force does the greatest magnitude of work on the crate
Consider all four forces. The normal force does no work at all, since there is no motion in the direction of that force, perpendicular to the ramp. The force of gravity is smaller than the force of friction, since you still need to push the crate to get constant velocity. The force of you pushing is also smaller than the force of friction, since you are moving down a ramp, and are therefore assisted by gravity. Therefore the force doing greatest magnitude of work is the force of friction. Note that, even though the frictional work is negative, it still has the greatest magnitude

Vas happenin!!!
Hope your day is good
I would say observational tool
Hope this helps

Answer:
position 3
Explanation:
in position 3 PE is least as height is least
so KE is most as energy is always conserved
Work is done when a force is applied to an object moves that object. the work is calculated by multiplying the force by the amount of movement of an object
