Force and motion chapter

Conclusion

How does the velocity from your prediction equation compare with the two measured velocities (measured with video analysis, and also with stopwatch / meter stick measurements) compare in each case? Did your measurements agree with your initial prediction? If not, why?

The situation this experiment was designed to test was launching cars with hanging wooden blocks. Does the launch velocity of the car depend on its mass? The mass of the block? The distance the block falls?

If the same mass block falls through the same distance, but you change the mass of the cart, does the force the string exerts on the cart change? Is the force of the string on the hanging object always equal to the weight of it? Is it ever equal to the weight of it? Explain your reasoning.
