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
neither gravitational potential energy nor kinetic energy.
only kinetic energy.
kinetic energy and gravitational potential energy.
only gravitational potential energy.

Answer 1

ok you remember the definition of potential energy I gave in your previous question?
well, water is moving, anything moving has kinetic energy
does that help?

Answer 2

Little

Answer 3

it b right

Answer 4

KE=1/2 mv^2
PE=mgh

At the top of the falls there is height.
Water is moving

Answer 5

nope, try again

Answer 6

c

Answer 7

bingo, both kinetic AND potential energy

Answer 8
