1
Q
What is the formula for useful work done?
A
Useful work done =
Work done (F×S) - Work done against friction (Fr × S)
Where Fr = frictional force
S = displacement
2
Q
How is change in kinetic energy related to work done?
A
∆KE = Work done
3
Q
How is change in kinetic energy related to work done involving friction and inclination?
A
∆KE = work done against friction + work done against force of inclination
Where force of inclination = mgsinθ
