The roller coaster is your favorite ride! But the line is always long! Having just studied potential and kinetic energy in physics, you evaluate the energy changes of the cars as they move on the tracks. Compare the potential energy of the cars if they are stopped at points A to point D.

• Neither have potential energy.

• The potential energy is the same.

• Potential energy is greatest at point D.

• Potential energy is greatest at point A.

Explain how the mass of a bowling ball that has been rolled down the lane affects the kinetic energy.

• The kinetic energy does not depend on the mass of the bowling ball.

• The kinetic energy is increasing proportional to the mass of the bowling ball.

• The kinetic energy is decreasing proportional to the mass of the bowling ball.

• The kinetic energy is increasing proportional to the square of the mass of the bowling ball.

What is the Law of Conservation of Energy?

• Energy cannot be created, but can be destroyed as it transforms.

• Energy can be created and destroyed as it converts to other forms.

• 
  Energy can be created and lost as heat as it converts to other forms.

• 
  Energy cannot be created nor destroyed only transformed to other forms.

A pole vaulter runs forward, plants his pole, rises in the air and lands. What point represents his greatest amount of gravitational potential energy?

• when he initially lands

• as he runs forward to plant the pole

• just before he starts to fall to the ground

• after take-off as the pole expands and lifts the vaulter toward the bar
