Activities

1. First, either specify lengths and angles for the two vectors, or get the simulation to do that by pressing the "Generate Vectors" button. It should be easy for you to fill in the lengths of the first two vectors. Then, figure out the components of the vectors and enter them in the table at the bottom of the simulation. Don't worry about filling in the "Resultant" line yet. Check your answers by pressing the "Check Answer" button at the bottom.
2. Once you have the components of the first two vectors correct, determine the components of the resultant vector (the resultant vector is the sum of the red vector and the blue vector). Enter those, and check your answers.
3. Finally, work out the magnitude and angle of the resultant vector. The angle is in degrees, measured counter-clockwise from the positive x-axis, which points to the right. Check your answers, and correct any mistakes.
4. Once you've solved the problem, get a new pair of vectors and try it all again to get more practice.
