1. Put several spoonfuls of flour in the bottom of the pan and spread it out
to make a level surface. 2. Now hold one mass cube above the surface of the flour and drop it. 3. Do the same with the other two mass cubes. 4. Now carefully lift each marble/rock out of the flour and look at the impact
craters. 5. Which mass cube made the smallest impact crater and why?
6. Which made the deepest impact crater and why?
7. Explain which of Newton's Laws this activity demonstrates?
1. This activity involves dropping mass cubes and marbles onto a surface of flour and observing the resulting impact craters.
2. The question specifically asks which mass cube made the smallest impact crater and why, and which made the deepest impact crater and why.
3. To answer these questions, the observations of the impact craters must be examined.
4. The mass cube that made the smallest impact crater likely had the least mass and/or the least velocity when dropped.
5. The mass cube that made the deepest impact crater likely had the most mass and/or the greatest velocity when dropped.
6. This activity demonstrates Newton's Second Law of Motion, which states that force equals mass times acceleration. As the mass of the dropped objects increases, the force of their impact on the flour also increases, causing larger and deeper impact craters.
