If you want to understand how an object (like a car, ball, person, or rocket) moves, you have to understand three things about what it means "to be moving." These three things "stick" to any object that moves, and are numbers that scientifically describe just how an object's motion is working. These three things are:

and..(the most difficult for most people)...

This selection allows you to play with the position, velocity, and acceleration for two objects at the same time. Try to learn about these three motion properties by comparing differences in your two objects' motion, for differently selected properties.

I'd like my first object to be a Big Red Truck Sport Utility Vehicle Motorcycle Scooter .

Start it at position 1 m 5 m 10 m 15 m 20 m Give it a speed of 0 meters/second 2.5 meters/second 5 meters/second 8 meters/second 10 meters/second Give it an acceleration of 0 meters/second*second 1 meters/second*second 2 meters/second*second 4 meters/second*second 6 meters/second*second 10 meters/second*second -1 meters/second*second -2 meters/second*second -4 meters/second*second

Give it a speed of 0 meters/second 2.5 meters/second 5 meters/second 8 meters/second 10 meters/second

Give it an acceleration of 0 meters/second*second 1 meters/second*second 2 meters/second*second 4 meters/second*second 6 meters/second*second 10 meters/second*second -1 meters/second*second -2 meters/second*second -4 meters/second*second
