2nd 9 week test review

At which location does the marble have the maximum kinetic energy?

• Location W

• Location X

• Location Y

• Location Z

Which of these correctly demonstrated the pontential energy and the kinetic energy of the bicycle rider?

• When the rider is at the top of the hill, the potential energy is the greatest, and kinetic energy the least

• As the rider moves up the hill, the kinetic energy increases and potential energy decreas

• When the rider goes down the hill the potential energy increases and the kinetic energy decreases,

• As the rider reaches the location of the hill, the kinetc enrgy and her potential energy decreases

Which statement best descrive the energy of the two planes?

• Airplane W has greater kinetic enrgy than Aiplane X

• The two airplanes have the same gravitational potential energy but different kinetic energies.

• Airplane X has more gravitational potential energy than Airplane W

• The two airplanes have the same kinetic energy but different gravitational potential energies

At which point is the gravitational potential energy of the water the greatest?

a

X

Z

Y

W
