Which piece of evidence supports "height increases, so does potential energy"?

• drop height of .75 has the greatest potential energy

• drop height of .5 has the greatest potential energy

• drop height of .25 has the greatest kinetic energy

• drop height does not increase the potential energy

Which piece of evidence supports "mass increases, so does potential energy"?

• mass does not affect potential energy

• mass of 6 has the greatest potential energy

• mass of 9 has the greatest potential energy

• mass of 3 has the greatest potential energy
