- 1 Names the gravitational potential energy store (or another explicitly allowed answer).
Full-mark answer
The gravitational potential energy store increases.
Why this answer loses marks
The water gains kinetic energy because it is moving.
The question asks which store increases when the water is uphill; use the change in height rather than the temporary pumping motion.
