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?

3. A scientist wanted to move a golf ball and a bowling ball to both reach 15 mph. What would the scientist have to do differently for the bowling ball than the golf ball to reach his goal?
Type Answer HERE:
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.

Directions for Set-Up
Before Pressing Go, which way do you think the cart will move? (None, Right, Left)
- Answer: It is impossible to determine without knowing the specific forces involved.
Why does the cart move that way?
- Answer: The cart will move in the direction where the net force is greater.
What is the sum & direction of the forces?
(example: 70 Left)
- Answer: The sum and direction of the forces will depend on the specific setup of the forces.
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

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?
Type Answer HERE:
- Answer: The student would expect to see that the cart with a mass of 50kg moves faster than the cart with a mass of 100kg. This is because the acceleration of an object is inversely proportional to its mass. Therefore, a lighter object will experience a greater acceleration for the same applied force.
3. A scientist wanted to move a golf ball and a bowling ball to both reach 15 mph. What would the scientist have to do differently for the bowling ball than the golf ball to reach his goal?
Type Answer HERE:
- Answer: To make both the golf ball and the bowling ball reach a speed of 15 mph, the scientist would have to apply a greater force to the bowling ball compared to the golf ball. This is because the mass of the bowling ball is greater than the mass of the golf ball, and according to Newton's second law of motion, the force required to accelerate an object is directly proportional to its mass.

II. Net Force Table:
1. Before pressing go, you need to determine which way you think the cart will move (None, Right, Left). This is a prediction based on the setup of the forces.
To make this prediction, you need to consider the forces acting on the cart. Look at the setup and determine which side has a greater force or if the forces are equal. If the forces are equal on both sides, the cart would not move (None). If the forces on the right side are greater, the cart would move to the right. If the forces on the left side are greater, the cart would move to the left.
2. To understand why the cart moves in a particular direction, you need to analyze the forces acting on it. Look at the setup and determine which side has a greater force. The cart will move in the direction of the larger force because the net force (sum of all forces) determines the motion. If one side has a greater force, it will overpower the force on the other side, causing the cart to move in that direction.
3. To determine the sum and direction of the forces, you need to count the number of small blue guys and red guys on each side. For example, if there are 2 small blue guys on the left rope and 1 small red guy on the right rope, the sum and direction of the forces would be 1 to the left (2-1=1). If there are 4 red guys on the right rope and a big blue guy on the left rope, the sum and direction of the forces would be 4 to the right (4-0=4).
III. Net Force Questions:
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 cancel each other out. The net force is zero in this case, resulting in no motion. Newton's first law of motion, also known as the law of inertia, states that an object at rest will stay at rest or an object in motion will continue moving at a constant velocity unless acted upon by an unbalanced force.
2. The student would expect the cart with a mass of 100kg to move slower than the cart with a mass of 50kg. This is because the force of 200 Newtons is divided by the mass of the cart to determine the acceleration. According to Newton's second law of motion (F=ma), the acceleration of an object is inversely proportional to its mass. Therefore, the cart with a larger mass would have a smaller acceleration and move slower compared to the cart with a smaller mass.
3. To make both the golf ball and the bowling ball reach 15 mph, the scientist would have to apply a greater force on the bowling ball. This is because the bowling ball has a greater mass compared to the golf ball. According to Newton's second law of motion (F=ma), the force required to accelerate an object is proportional to its mass. Since the bowling ball has a greater mass, a larger force would be needed to achieve the same acceleration as the golf ball.
