what is moment in science?
i never seem to understand
i never seem to understand
A moment is a tendency of a force to rotate an object around an axis. If normal forces are push and pull, a moment can be thought of as a twist.
In simple terms, it can be considered as a turning force on an object.

how do you figure it out

how do you figure it out
The simple equation for moments is where F is the force applied and d is the perpendicular distance from the pivot. The SI unit is Newton meters.

By this I assume you mean how to work out the moment of a force? The equation is:
Force (acting on the object) x perpendicular distance from the pivot to the point where the force is acting

the part with the perpendicular distance......
can you put this in a formula triangle???

Take a look at the link in my post. It probably got there after you posted.

Perpendicular means at right angles, so you only take the distance at right angles to the direction of the force.
Yes, but rearranging equations is an essential skill to have.

Moment
Force x distance
That's the best triangle I can do

Of course.
I am a secondary school student as well.

9 what about you
Original post by majmuh24
You're hardly the average secondary school student though
You probably know more maths (and are better at it) than most people who have sat A Level maths.
