Instructor: Ma. Beata B. Mijares
Experiment/Activity No. 11 Conservation of Momentum in Explosion
I. Objectives
•
To demonstrate the conservation of momentum for two carts pushing away from each other.
II. Materials and sit-up Apparatus
•
Dynamic Cart with Mass (ME-9430)
•
Collision Cart (ME-9454)
•
Dynamic Cart Track
•
Meter Stick
•
Mass Balance
III. Theory of the experiment In many subfields of physics these days, it is possible to read an entire issue of a journal without ever encountering an equation involving force or a reference to Newton's laws of motion. In the last hundred and fifty years, an entirely different framework has been developed for physics, based on conservation laws. The new approach is not just preferred because it is in fashion. It applies inside an atom or near a black hole, where Newton's laws do not. Even in everyday situations the new approach can be superior. We have already seen how perpetual motion machines could be designed that were too complex to be easily debunked by Newton's
laws. The beauty of conservation laws is that they tell us something must remain the same, regardless of the complexity of the process.

V. Analysis of Data and Result
VI. Answer to guide question
1. Does the ratio of the distances equal to the ratio of the masses in each of the cases? In other words, is momentum conserved?
2. When carts of unequal masses push away from each other, which cart has more momentum?
3. When the carts of unequal masses push away from each other, which cart has more kinetic energy?
4. Is the starting position dependent on which cart has its plunger cocked? Why?
VII. Conclusion
