**Virtual Activity: Working with Vectors**In this activity you will practice adding vectors together.

**Check the show grid box.**

Drag a vector from the bin.

Choose "style 1" in the component display box.

Change the size and orientation of the vector by moving its tip to various locations.

Drag a second vector out of the bin.

Click the "Show Sum" box to see the addition of the vectors.

Please note that the angle is measured from the + x axis and that an angle of -90° is equivalent to an angle of 270° and so forth.

Problem 1: In your lab notebook, calculate the sum of the following three vectors:

Vector **A**: magnitude = 9.4, angle = 32.0°

Vector **B**: magnitude = 13.7, angle = 59.7°

Vector **C**: magnitude = 15.0, angle = -143.1°

Now use the simulation to connect these vectors head to tail. Click the show sum box and compare your answer to that given in the simulation. You should slide the resultant vector into the space from the tail of vector **A** to the head of vector **C**.

Problem 2: In your lab notebook, calculate the sum of the following three vectors:

Vector **D**: magnitude = 17.1, angle = 159.4°

Vector **E**: magnitude = 6.4, angle = -51.3°

Vector **F**: magnitude = 12.0, angle = 4.8°

Now use the simulation to connect these vectors head to tail. Click the show sum box and compare your answer to that given in the simulation. You should slide the resultant vector into the space from the tail of vector **D** to the head of vector **F**.

Play around a bit! Have fun!
