Sure. Consider a good old Tug 'o War, with 3 or more strong guys pulling in
various directions, and that big old knot in the middle of the rope right over the
mud pit isn't moving an inch. (Remember, it would move immediately if the net
force on it were not zero.)
Maybe an even better example is to consider 50 people evenly distributed all
the way around a small car, all pushing on the car in different directions. It's
very plausible that the car doesn't roll at all ... the net force on it is zero.
An equilateral triangle is made up of three vectors that sum up to zero.
-- A singe vector with a magnitude of zero produces a zero resultant.-- Two vectors with equal magnitudes and opposite directions produce a zero resultant.
Thee direction of the two vectors.
No. The tenth vector would have to be matched by one equal and opposite vector to yield a zero resultant, or by multiple vectors in the second plain collectively yielding a zero resultant for that plane. It would be possible, for example, for 8 vectors to be on the same plane and two on a different plane to give a zero resultant.
The zero-vector has no direction.
No.
Assuming you want non-zero vectors, two opposing vectors will give a resultant of zero.
-- A singe vector with a magnitude of zero produces a zero resultant.-- Two vectors with equal magnitudes and opposite directions produce a zero resultant.
Take any three vectors in a plane which, when placed end-to-end form a triangle. The resultant of the three vectors will be zero.
Two - if you add two vectors of equal magnitude but in opposite directions, the resultant vector is zero.
opposite
The resultant of two vectors is a third vector., for example V1 + V2 = V3. V3 may be equal to zero, greater than zero or less than zero.
Thee direction of the two vectors.
No. The tenth vector would have to be matched by one equal and opposite vector to yield a zero resultant, or by multiple vectors in the second plain collectively yielding a zero resultant for that plane. It would be possible, for example, for 8 vectors to be on the same plane and two on a different plane to give a zero resultant.
It is certain that two vectors of different magnitudes cannot yield a zero resultant force.
The zero-vector has no direction.
A triangle of vectors, in which the sides are the three vectors arranged head-tail.
No.
