# How do you find the resultant using the polygon method?

|In polygon method of finding the sum or resultant of vectors →P,→Q, →R,→S,→T , are vectors are drawn from head to tail to form an open polygon, as shown. The starting point A is arbitrary. The resultant vector →R is drawn from the tail of first vector to head of the last vector.

**Polygon method** in physics is the extension of triangle law of vector addition. It state that if a number of vectors can be represented by the side of the **polygon** in magnitude and direction taken in order, then their resultant is represented by the side which close the **polygon** taken in the opposite order.

Subsequently, question is, what is the parallelogram method? **Parallelogram method** is a **method** for finding sum or resultant of two vectors. The polygon **method** is a **method** for finding sum or resultant of more than two vectors. (Can be used for two vectors also).

Likewise, how do you use the graphical method to solve the resultant vector?

The **graphical method** of adding **vectors** A and B involves drawing **vectors** on a graph and adding them **using** the head-to-tail **method**. The **resultant vector** R is defined such that A + B = R. The magnitude and direction of R are then determined with a ruler and protractor, respectively.

What is the polygon law of vector addition?

**Polygon law of vector addition** states that if a number of **vectors** can be represented in magnitude and direction by the sides of a **polygon** taken in the same order, then their resultant is represented in magnitude and direction by the closing side of the **polygon** taken in the opposite order.

### What is the resultant displacement?

The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. When displacement vectors are added, the result is a resultant displacement.

### What is the formula for resultant force?

Notice that the case of two equal but opposite forces F and -F acting at points A and B respectively, yields the resultant W=(F-F, A×F – B× F) = (0, (A-B)×F).

### How do you find the displacement?

To calculate displacement, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. In physics, displacement is represented by Δs.

### What is the meaning of resultant force?

A resultant force, also called a net force, is a force equal to the sum of all forces applied to an object.

### What is a negative vector?

A negative vector is a vector which points in the direction opposite to the reference positive direction. A negative vector is a vector that has the opposite direction to the reference positive direction. Like scalars, vectors can also be added and subtracted.
