Distance
How much ground an object
has covered
Velocity
How fast an object is going in a
certain direction.
Acceleration
How quickly an object speeds up or
slows down.
Force
A push or pull that causes an object to

To Play:
•
Select your settings. Once you have the settings you want, Click Start Game.
•
The players take turns lining up shots or running (Hyperspace). Every action takes place after
everyone has taken their turn.
•
When it is your turn, select how you want to shoot. You can click inside the white circle and also
use the Angle and Power bars to control your shot. (Hint: Get a shot you like by clicking in the
circle, then fine tune it with the bars.) If you think you are in too much danger, hit Hyperspace to
try to escape to a safer location.
•
When ready, select End Turn to move to the next station or player.
•
Be the last station alive to win. Don’t forget that gravity will affect your shots!
