Only if the two velocities are equal in magnitude but in opposite directions.
the principle that resultant of the external forces and kinetic reaction acting forces is zero
The resultant vector has maximum magnitude if the vectors act in concert. That is, if the angle between them is 0 radians (or degrees). The magnitude of the resultant is the sum of the magnitudes of the vectors.For two vectors, the resultant is a minimum if the vectors act in opposition, that is the angle between them is pi radians (180 degrees). In this case the resultant has a magnitude that is equal to the difference between the two vectors' magnitudes, and it acts in the direction of the larger vector.At all other angles, the resultant vector has intermediate magnitudes.
There is no negative zero or positive zero, zero is just zero so you can take it off. For example: 3-2-0= just 3-2
The derivate of zero - as well as the derivative of ANY constant (non-variable) number, is zero. (A graph of y = 0 for example will be a horizontal line - the slope is zero.)
Zero represents a set with no elements.The purpose of zero as a digit: In our decimal numbering system, in any number you use, for example 512, each of the digits has its own value, but it also has a value that depends on its position. For example, 5 is not simply 5, it is 5x100, because of the position where it appears. Often, a zero will be needed as a placeholder, to "push" other digits further to the left. For example, 107 is not the same as 17. The zero is required to put the 1 "into its rightful place".
A couple.
[object Object]
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
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.
A system is in equilibrium if: 1. The resultant force on it is zero. 2. The resultant torque on it is zero. Note that for a system which is a point object, only condition 1 is necessary for the system to be in equilibrium.
Sure. For one example, if their magnitudes are equal and their directions are spaced 120 degrees apart, then they add to zero. There are an infinite number of other sets of magnitudes and directions that add to zero, i.e. have a zero resultant.
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.
Not necessarily zero; it depends. For example two people on a sse saw at same weight and same distance from fulcrum is zero moment but there is force at fulcrum equal to twice their individual weight
The zero-vector has no direction.
Assuming you want non-zero vectors, two opposing vectors will give a resultant of zero.
Absolutely.A very simple example: 10 pounds north, 6 pounds south, 4 pounds south.How about the resultant of 100 vectors being equal to zero, as in a tug-of-war with50 guys on each side !
The condition where the net force on an object is zero ,the body is said to be in equilibrium.As net forces are zero.
