That depends on how you are using the vectors. If a person moves from A to B and then from B to C, you can add two motion vectors AB and BC to get the total motion vector AC. But force doesn't work that way.prashant singh said:I think this question doesn't makes any sense because vector algebra is applied for simooultaneous vectors(here force). I think direction doesn't matters but u can take both in same direction.
The magnitudes of the forces add like this only if the forces are acting in the same direction.prashant singh said:Suppose if I applied a 4N force and then 2N force on an object , what will be total force. Note I didn't said simoultaneously, I mean one after the other, then what will be the total force , I think 6N
Of course the direction matters.prashant singh said:I think direction doesn't matters but u can take both in same direction.

Of course the direction matters.
Also, "textspeak" such as "u" for "you" is not allowed at this site.

I don't think that makes sense. If you have some object that is moving along a path, and you apply a force to it, that force could cause the object to change direction (or not, all depending on the direction of the force and the direction the object is moving). If later a different force is applied, then that could cause a different resulting direction for the object. To the best of my knowledge, you don't add vectors that aren't acting simultaneously (simoultaneously is not a word).prashant singh said:Can we add two vectors which are not acting simoultaneously by the vector law of addition.

Also, if the two forces are applied at different times (i.e., not simultaneously), how much time elapses between the times of the two forces? One second, one hour, one week, ten years?
You can if it makes sense for the context of the situation . For instance a displacement of 3km due north followed by a displacement of 4km due east. Those displacement vectors can be added to give the overall displacement.prashant singh said:Can we add two vectors which are not acting simoultaneously by the vector law of addition.
A vector is a quantity that has both magnitude and direction. It is often represented by an arrow, with the length of the arrow representing the magnitude and the direction of the arrow representing the direction.
To add vectors, you must first ensure that they are in the same direction. Then, you can simply add the magnitudes of the vectors to get the resulting magnitude. The direction of the resulting vector can be found using trigonometric functions.
A scalar is a quantity that only has magnitude, while a vector has both magnitude and direction. Some examples of scalars are temperature, mass, and time. Examples of vectors include velocity, force, and displacement.
Yes, vectors can have negative magnitudes. This indicates that the vector is pointing in the opposite direction of its positive counterpart. For example, a vector with a magnitude of -5 will have the same direction as a vector with a magnitude of 5, but will be pointing in the opposite direction.
The vector sum, also known as vector addition, is the process of combining two or more vectors to get a resulting vector. The vector product, on the other hand, is the process of multiplying two vectors to get a resulting scalar or vector. There are different types of vector products, such as dot product and cross product, which have different calculations and applications.
