# Physics moments??? watch

1. Pls can anyone help me with moments. I'll message you the questions?
2. Sorry you've not had any responses about this. Are you sure you've posted in the right place? Here's a link to our subject forum which should help get you more responses if you post there.

Just quoting in Fox Corner so she can move the thread if needed

If it's GCSE then I can help
4. Post actual question in the forum. I dont know why you have to message it to individuals?
5. I am a qualified physics teacher, I can definitely help

Pls can u explain to me how you would answer this question?
7. Part a) moment = Force x perpendicular distance so F1 = 3x3 = 9nm
F2 = 12 x 3 = 36nm
F3 = 3 x 22 = 66nm
F4 = 3 x 23 = 69nm

part b) F1 anticlockwise
F2 Anticlockwise
F3 Clockwise
F4 Clockwise

part c) Resultant moment = total clockwise moments - total clockwise moments
= (F3 + F4) - (F1 + F2)
= 135 - 46
= 89nm clockwise

I would suggest you write the unit for moment of force as N m. In physics, nm represents nanometre or nanometer.
9. Yeah thanks. usually do when writing out by hand.

Sorry I am late to the party, but it seems that the question has been answered correctly. The only thing missing is the explanation behind it. This 6 min video will explain it and give other examples:-
