## Adding Vectors End to End

#### High School - HSN-VM.B.4b

How to Add Vectors End to End - Adding vectors can sometimes be a complicated procedure. Here are a few procedures with steps that can help you add your vectors from end to end. Explanation #1 - The first step that is involved you have to find the sum of each of the vectors. Second step includes drawing the lines that indicate and model the vectors. Step three involves counting the blocks that have been covered by the two vectors: x = 3 y = 4 Step four involves finding magnitude of the the resultant vector. For this step the most common approach is using the Pythagoras Theorem which is: a2 + b2 = c2 The resultant vectors in this case will be: x2 + y2 = r2 or 32 + 42 = r2 | r = √ (32 + 42) | r = 5 Explanation #2 - The first step involves understanding what is being asked in the question which is usually going to be "find the sum of the vectors". The second step is to draw those legs again and see where they fall. Step three involves the same step as previous one, counting the number of blocks covered by each vector: x = 5, y = 5 The fourth step is finding the resultant factor using the Pythagorean theorem: a2 + b2 = c2 The resultant vector is: 52 + 52 = r2 | The resultant is r = √ (52 + 52) | r = 7.07. This worksheet series shows students how to use vector addition to find the end result of two vectors which in motion is usually a measure of net force.

### Printable Worksheets And Lessons  #### Homework Sheets

This skill is often studying early on in physics.

• Homework 1 - Count the number of blocks covered by two vectors.
• Homework 2 - The vectors are plotted and the resultant is the hypotenuse.
• Homework 3 - This is a useful strategy to visually respresent the movement of an object.

#### Practice Worksheets

This is sometimes referred to as Impact Science. You can use this skill to estimate or calculate levels of damage in car accidents.

• Practice 1 - Find the sum of each pair of vectors (the magnitude of the resultant vector).
• Practice 2 - To find the resultant vector's magnitude, use the Pythagorean Theorem.
• Practice 3 - The resultant is: x2 + y2 = r2
