Question

If we decrease the amount of force, and kelp all other factors the same, what will happen to the amount of work?

A. The amount of work will go down because the distance will decrease

B. The amount of work will go up because the distance will decrease

C. The amount of work will go up because the distance will increase

D. The amount of work will go down because the distance will increase

Answer 1

Distance will decrease and work will decrease:

F = m a Newton's Second Law

a = F / m decreasing force will decrease acceleration

S = 1/2 a t^2 = 1/2 (F / m) t^2 distance traveled will decrease as force decreases

W = F * S work will decrease as both force and distance decrease
