II. Net Force Table:

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

Place the medium blue guy on the very end of the left rope & 1 small red guy on the very end of the right rope

Place the big blue guy on the very end of the left rope & add all 4 of the red guys to the right rope

III. Net Force Questions:

1. If you have an equal amount of force on both sides of the tug of war cart, what happens every time? Explain Why.
Type Answer HERE:
2. A student wanted to investigate changing the mass of a cart that you can push. The student pushed both carts with a force of 200 Newtons. If one cart has a mass of 100kg and the other cart a mass of 50kg, what results would the student expect to see as far as how fast each cart moved in comparison with one another?

1. If you have an equal amount of force on both sides of the tug of war cart, the cart will not move. This is because the forces on each side cancel each other out, resulting in a net force of zero.

2. The student would expect the cart with a mass of 50kg to move faster than the cart with a mass of 100kg. This is because the force of 200 Newtons is the same for both carts, but the cart with lower mass will experience a greater acceleration according to Newton's second law (F=ma).

3. To move the bowling ball to reach 15 mph, the scientist would have to apply a greater force compared to the golf ball. This is because the bowling ball has a greater mass, and according to Newton's second law, a greater force is required to accelerate an object with greater mass to the same speed.
