Define moment of of force and 5 example

It defined as movement of measure of tendency to cause a body to rotate about its specific axis

M=F*d

Where F is the applied force and d is the distance

measuring things 1 litre of water

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
