Predict what would happen if you dropped a 1 lb ball from 10ft in the air into sand and measured the size of the crater, and then a 10lb ball from 10ft in the air and then measured the size of the crater.

Answer 1

If you drop a 1 lb ball from 10 ft in the air into sand and measure the size of the crater, and then a 10 lb ball from 10 ft in the air and measure the size of the crater, you would expect to see that the crater created by the 10 lb ball is larger than the crater created by the 1 lb ball. This is because the larger mass of the 10 lb ball will result in a greater impact force upon hitting the sand, which in turn will cause a larger excavation of the sand and thus a larger crater.
