Question

) While rotating an object or while
opening a door or a water tap we apply a
force or forces. Under which conditions
is this process easy for us? Why? Define
the vector quantity concerned. How does
it differ for a single force and for two
opposite forces with different lines of
action?​

Answer 1

Explanation:

we are using a little amount of force because it's easy for us why because the mass of the water tap is less than the mass of our hand and the vector quantity concerned is zero because for vector quantity you need a magnitude and speed and the direction and while turning a tab automating an object it does not make any movement but just it comes back to its position and also we do not use two or more forces because the tap the water tab is just rotating by the force of a hand there is no opposite force that react that is reacting on our hand so please please please please please please mark this answer as the r
