Directions: Follow the link to the second law computer experiment and then collect data on time and acceleration for 10 totally different cart weights and ten totally different hanging mass weights.
When you are done you should answer the following analysis questions:
1. What effect does adding mass to the cart have on acceleration?
2. What effect does lowering mass to the cart have on acceleration?
3. What effect does increasing mass on the hanging weight have on acceleration?
4. What causes the downward force on the hanging mass?
5. What is the formula that links force, mass and acceleration? and what is it called?
6. If a 1 kg falling mass pulls a 1 kg cart what is the acceleration?
7. How does this lab relate to the way your car would accelerate when pulling a trailer or loaded with passengers?
8. What would the physics justification be for limiting the number of passengers for new drivers?
