The pull of gravity on the surface of the moon

When one ball is raised, it acquires potential energy which is then transformed into kinetic energy once the ball is released. In theory, the total energy should be conserved such that the balls continue in perpetual motion.

A student conducts an experiment to determine how the additional of salt to water affects the density of the water. The student fills 3 beakers with equal amounts of water.
