Question

When a wall is pished it does not move from its place .Is any workdone in this situation . why?

Answer 1

✔️✔️YOUR ANSWER ✔️✔️

When a wall is pushed it doesn't move from its place. So, no work is done

✨✨✨REASON✨✨✨

WORK = FORCE APPLIED * DISPLACEMENT

WE KNOW,
WORK IS ALWAYS SAID TO DONE WHEN A FORCE ACT ON A BODY AND IT PRODUCES MOTION

BUT HERE◀️◀️
WE CAN SEE....
A PERSON IS APPLYING A FORCE ON A WALL BUT THERE NO DISPLACEMENT SO, NO WORK IS DONE

⭐️LETS UNDERSTAND IT CLEARLY..

SUPPOSE A PERSON IS APPLYING 100 NEWTON FORCE ON WALL BUT THERE IS NO DISPLACEMENT

USING FORMULA-
WORK = FORCE * DISPLACEMENT
WORK = 100N * 0 (NO DISPLACEMENT)
= O
SO, THE WORK WILL ALSO BE ZERO


✔️✔️HOPE IT WILL HLP U

Answer 2

EXPLANATION:::::No, there is no work done by that person.if however,the distance moved is zero then the work done on an object is always zero. For ex-a man is completely exhausted in trying to push a stationary wall ,but since there is no displacement, the work done by the man is zero
