what is vector???write some formula related to it
Answers
Answer:
the rate of change of displacement
Answer:
A vector is an object that has both a magnitude and a direction. In Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction.
Vector is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity magnitude. Vector quantities are often represented by scaled vector diagrams. The vector diagram depicts a displacement vector.
Triangular law of addition
If two forces Vector A and Vector B are acting in the same direction, then its resultant R will be the sum of two vectors.
Formula for Triangular law of addition:
R
⃗ = A
⃗ + B
⃗
Parallelogram law of addition
If two forces Vector A and Vector B are represented by the adjacent sides of the parallelogram, then their resultant is represented by the diagonal of a parallelogram drawn from the same point.
Formula for Parallelogram law of Addition:
R
⃗ = A
⃗ + B
⃗
Vector Subtraction
If two forces Vector A and Vector B are acting in the direction opposite to each other then their resultant R is represented by the difference between the two vectors.
Formula for Vector Subtraction:
R
⃗ =
A ⃗
− B
