In its most simple and basic form, a moment is the product of the distance to some point, raised to some power, and some physical quantity such as the force, charge, etc.
at that point: where is the physical quantity such as a force applied at a point, or a point charge, or a point mass, etc..
What are the applications of moments?
If a body is in rotational equilibrium then the sum of the anticlockwise moments is equal to the sum of the clockwise moments. OR If a body is in rotational equilibrium then the algebraic sum of the moments about any point is zero. Applications of Principle of Moments: To find the mass of an object.
What is Moment example?
A moment is the name for the turning effect that forces exert on objects. For example imagine pushing a door open. You push on the door handle and the door rotates around its hinges (the hinges are a pivot). … The larger the perpendicular distance the larger the turning effect (moment).

How do you measure a moment?
The Moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis. … The magnitude of the moment of a force acting about a point or axis is directly proportinoal to the distance of the force from the point or axis. … Moment = Force x Distance or M = (F)(d)More items…
Why is it called moment?

How long is a jiffy in time?
In astrophysics and quantum physics a jiffy is, as defined by Edward R. Harrison, the time it takes for light to travel one fermi, which is approximately the size of a nucleon. One fermi is 10−15 m, so a jiffy is about 3 × 10−24 seconds.
