Question

what is the best way to move a heavy box so that least force is applied ? explain with reason

Answer 1

Reduce the friction of the surface on which it is kept , you have to apply less force & it will move very easily ,

Answer 2

we have to apply rollers for it so that we can move a heavy box easily
one reason is round objects have always less contact friction,so as the friction is less static friction comes into play which helps us to move a heavy box easily;just like a heavy man who is 399kgs slides easily on the floor
