Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero. Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.

## Under what condition the sum of three vectors is zero?

If magnitude of resultant of two vectors is exactly equal to the magnitude of the third vector. If direction of resultant of those two vectors is exactly opposite to the direction of the third vector. If all above conditions are satisfied, then the resultant of three vectors will be zero.

## What happens when two vectors are added?

The sum of two or more vectors is called the resultant.

## What is difference between phasor diagram and vector diagram?

Although the both the terms vectors and phasors are used to describe a rotating line that itself has both magnitude and direction, the main difference between the two is that a vectors magnitude is the “peak value” of the sinusoid while a phasors magnitude is the “rms value” of the sinusoid.

## What is space diagram vector diagram?

The space diagram takes care of the point of application of forces and the geometry of the truss. The above shown figure is only to get the reactions. Applied force is ab and force is bc in the vector diagram. Reaction is equal to da and Reaction is equal to cd in the vector diagram.

## What is possibility diagram?

A Probability Space Diagram, or Sample Space Diagram, shows information about event outcomes in a structured view. Space diagrams are normally used to show the possible combination of two events. The information held in the grid depends upon the events being recorded.

## Where are vectors used in everyday life?

Vectors have many real-life applications, including situations involving force or velocity. For example, consider the forces acting on a boat crossing a river. The boat’s motor generates a force in one direction, and the current of the river generates a force in another direction. Both forces are vectors.

## Why do we use kinematics?

Kinematics aims to provide a description of the spatial position of bodies or systems of material particles, the rate at which the particles are moving (velocity), and the rate at which their velocity is changing (acceleration).
