Vector addition using graphical method

[Turn09]

Hello,

How do I use the graphical method of vector addition to determine the magnitude and direction of the resultant displacement? Just the steps on how to determine displacement vectors??

Hello Turn09! Welcome to PF!

This is the vector triangle method …

just draw the two given vectors, with arrows, and join their ends …

the third side of the triangle is the vector you want.

(The only tricky part is getting the arrows the right way round, to make sure (by following the arrows) that you've stuck the second vector on the correct end of the first vector! )

To determine the magnitude and direction of the resultant displacement using the graphical method of vector addition, follow these steps:

1. Draw a scale diagram: Start by drawing a scale diagram of the given vectors. Choose a suitable scale and draw the vectors in the correct direction and magnitude, according to the given information. Make sure to label the vectors and include a reference point.

2. Choose a reference direction: Choose a reference direction, usually horizontal or vertical, and draw a reference line from the reference point to the end of the first vector.

3. Add the vectors: To add two vectors, simply place the tail of the second vector at the head of the first vector. The line drawn from the tail of the first vector to the head of the second vector represents the resultant vector.

4. Measure the magnitude: To determine the magnitude of the resultant vector, use a ruler to measure the length of the resultant vector on the scale diagram. This will give you the magnitude of the resultant displacement.

5. Determine the direction: To determine the direction of the resultant displacement, use a protractor to measure the angle between the reference direction and the resultant vector. The direction of the resultant displacement is the angle measured from the reference direction in the direction of the resultant vector.

6. Check for accuracy: Make sure to check your calculations and measurements to ensure accuracy.

Overall, the graphical method of vector addition is a visual and intuitive way to determine the magnitude and direction of the resultant displacement. It is important to accurately draw the scale diagram and follow the steps carefully to get accurate results.
