3. What methods are you using to test this (or each) hypothesis?

To test this theory I used balls and measured their mass, volume, density, and the amount of displaced water or how much a tube would be filled up if the ball was placed inside.

For Example:

In the experiment where I used Table B, I filled a bucket up with water and predicted whether or not an inflated football would float if I put it in the water, then I measured the amount of displaced water from putting the inflated football in the bucket, which was 4000 mL. Then I did the exact same thing but with a deflated football, the amount of displaced water was 500 mL.

Explanation: This is the answer I put on edg

less than one you can't create energy

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
