Directions for Set-Up
Before Pressing Go, which way do you think the cart will move? (None, Right, Left)
Why does the cart move that way?
What is the sum & direction of the forces?
(example: 70 Left)
Place 1 small blue guy on the very end of the left rope & 1 small red guy on the very end of the right rope
Before pressing Go, the cart will move to the right. This is because there is a greater net force acting on the cart in the right direction.
The cart moves to the right because the net force acting on it is greater in that direction. The net force is determined by adding up all the individual forces acting on the cart.

The sum and direction of the forces can vary depending on the specific setup and weight distribution of the cart.
