Question

Niagara Falls is a set of very large waterfalls located on the border between New York and Ontario, Canada. Over 200,000 cubic feet of fast-moving water falls approximately 180 feet every second. Water at the top of the Falls possesses
kinetic energy and gravitational potential energy.
only gravitational potential energy.
only kinetic energy.
neither gravitational potential energy nor kinetic energy.

Answer 1

The first choice is correct.  It has both.

-- It has kinetic energy because it's "fast-moving" water.

-- It has gravitational potential energy because it's hundreds of feet
above the riverbed that it's getting ready to fall down to, as soon as
it goes over the edge.

Answer 2

Yep its A-kinetic energy and gravitational potential energy
