Vector Addition

Click and drag simulation for any 2D vector addition problem

This simulation is designed for physics teachers and students. Touch and drag to draw 2D vectors on screen, connect them and see the resultant. This is a teaching/learning tool for students to be able to draw and visualize vector addition with immediate feedback.

Instructions:

- touch and drag to draw a vector (maximum 2 allowed at a time)

- drag the ends to change the vector, or the center to translate it across the screen and connect it to another vector

- "snap 5/2" - snaps vectors to the nearest 2 m and 5 degrees to make them easier to draw

- "values" displays or hides the magnitudes and angles of the drawn vectors

- "answer" displays or hides the magnitude and direction of the resultant

- "?" creates a random 2D vector addition problem on the left for users to simulate

- click on the bottom right to reset the app

- the "scale" bar at the top can be dragged to allow different scales to fit on screen
