Conditions of Use
ELASTIC MAN TO THE RESCUE!!!!!!!
Okay so here is how you propel A Cart across a floor.
1.Get a cart.
2.Get a rubber band.
3.tie the rubber band around 2 of the wheels that are on the cart.
4.twist the rubber band and let go.
5.watch the cart run around. :D
And the difference between mass and weight.
Mass can have a bunch of weight, or it can not have a bunch of weight. And it has ummm.....density! So yeah. And weight is normally measured in pounds. :3 It depends on how much mass the object has to know how much it weighs.
PS this post is confusing......to me.
