Lab - Energy and Rollercoaster

The Rollercoaster track gets attached to the stand at hole

• 5 from the top.

• 4 from the bottom.

• 3 from the bottom.

• 5 from the bottom.

When attaching the photogate to the rollercoaster track, the photogate

• should always be perpendicular to the track.

• should be straight up and down relative to the table.

You have to add the height of the stand base for...

• the first position on the rollercoaster track only.

• all of the positions on the rollercoaster track.

• the three lowest positions on the rollercoaster track only.

Why is 0.019 meters used when calculating the speed of the marble?

• No particular reason other than to be consistent.

• It is the width of the beam in the photogate.

• It is the width of the flag on the car.

• It is the diameter of the marble.

When calculating Potential Energy, height has to be in 

• centimeters

• meters.

• feet

• inches
