In the lab you will measure the forces that two carts exert on one another in various situations, such as when they collide or when one is pushing or pulling the other. Here you will make some predictions about these forces, and come up with situations to test in the lab.

Click the button above to run the simulation, which will show four situations involving two carts. For each case predict which cart experiences a larger-magnitude force by circling one of the choices below.

Case 1: | cart 1 feels more force | cart 2 feels more force | forces are equal |
---|---|---|---|

Case 2: | cart 1 feels more force | cart 2 feels more force | forces are equal |

Case 3: | cart 1 feels more force | cart 2 feels more force | forces are equal |

Case 4: | cart 1 feels more force | cart 2 feels more force | forces are equal |

Come up with a few collision situations where you think the forces the two carts exert on one another will be of **equal** magnitude. Briefly describe these situations.

Come up with a few collision situations where you think the forces the two carts exert on one another will be of **different** magnitude. Briefly describe these situations.

Come up with a few situations where one cart is pushing or pulling the other and you think the forces the two carts exert on one another will be of **equal** magnitude. Briefly describe these situations.

Come up with a few situations where one cart is pushing or pulling the other and you think the forces the two carts exert on one another will be of **different** magnitude. Briefly describe these situations.
