Move the car around the screen by changing the magnitude and direction of the blue vector. If you check the
Show Cyclone box, a cyclone will appear somewhere on the screen. Try to intercept it—but be careful not to hit the walls!
In this version of the game, the cyclone is stationary. In Vector Investigation: Car Storm Chaser, Moving Target, try to catch a cyclone that moves!

The magnitude and direction of the vector can be changed by (1) using the mouse to drag either end of the arrow or (2) adjusting the sliders for magnitude and direction below the screen. Click and drag the middle point of the arrow to relocate the vector.
The Start/Stop Car button puts the car in motion and stops it. The Reset Car button returns the car to its original location.
Show Cyclone makes the cyclone visible. Show Grid places the velocity vector on a grid, and Sound On turns the sound on or off.
