3. varying projectile mass

The problem of this experiment will be something like “I want to find out if heavier projectiles make bigger craters.”

By now, you will probably have got the hang of it. In this experiment, just vary the mass of the projectiles (steel, glass, wood, foam etc.), not their diameters or the height from which you drop them.

Materials:

1-7

8. Small scale. An electronic scale or balance is ideal to determine the mass of the projectiles.Make a table noting the projectile masses and crater diameters and construct a new graph.Make an other table noting the projectile masses and ejecta ray lengths and construct a graph.
