Suppose two coolies , Coolie A and Coolie B lifts a same load on a roof of bus in 1 minute and 2 minutes respectively , they both do same work.
My confusion is that :
We know , Work = Force × Displacement
Here the distance remains same from ground to roof.
But my question is that how the force remains same since Coolie A takes less time than coolie B then force of coolie A must be less than coolie B hence work should be different. Then how work done is same?
Yes I am an Indian . When force is applied at different velocities how can the force be same. Suppose i kicked a ball running 50 km per hour and you kicked it running 100 km per hour . You must have put greater force than me.then how both the forces are same ?
