Yes, by checking to see if they are simply transformations of each other and removing those transformations.
If they are equal in magnitude but act in opposite directions.
The minimum possible magnitude that results from the combintion of two vectors is zero. That's what happens when the two vectors have equal magnitudes and opposite directions.The maximum possible magnitude that results from the combintion of two vectors is the sum of the two individual magnitudes. That's what happens when the two vectors have the same direction.
If two vectors are represented by the same magnitude and direction they are said to be equal.
Yes.
Yes. This will happen if the two vectors are at an angle of 120 degrees.
When the angle between two vectors is zero ... i.e. the vectors are parallel ... their sum is a vector in thesame direction, and with magnitude equal to the sum of the magnitudes of the two original vectors.
Yes, if the three vectors are starting from the same point and are directed at 120 degrees between each two vectors.
Equal vectors are vectors having same direction of action or orientation as well as same magnitude. If two or more vectors have same magnitude but different direction then they cannot be called equal vectors. This shows that direction is important for equal vectors.
only if the vectors have the same direction
Two vectors: no. Three vectors: yes.
Yes, if one of the vectors is the null vector.
Not really. The sum of the magnitudes is a scalar, not a vector - so they can't be equal. But the sum of the two vectors can have the same magnitude, if both vectors point in the same direction.
