Multiple Choice Question

Question

Students are investigating energy transfer in the laboratory. The students use rubber bands and rulers for their investigation. They attach a rubber band to each ruler, pull the band back, and allow the band to launch from the ruler. The diagram shows their set up.

The results of their investigation are shown.

Ruler Distance Band Is Pulled Back
(centimeters) Distance Band Travels (centimeters)
1 5 61
2 10 122
3 15 213
4 20 366
Which statement best describes the results of their investigation?
A.
The more potential energy the band has, the more kinetic energy is transferred, and the farther the band travels.

B.
The less potential energy the band has, the more kinetic energy is transferred, and the farther the band travels.

C.
The more kinetic energy the band has, the more potential energy is transferred, and the farther the band travels.

D.
The less kinetic energy the band has, the more potential energy is transferred, and the farther the band travels.

Answer 1

A. The more potential energy the band has, the more kinetic energy is transferred, and the farther the band travels.

Answer 2

A student is investigating the transfer of potential energy into kinetic energy. The student uses a slingshot and a marble, as shown in the diagram.

The steps of the student's investigation are shown.

Step 1 Place the marble in the slingshot, pull back on the sling to a distance of 15 centimeters, release the sling, and record the distance the marble travels.
Step 2 Place the marble in the slingshot, pull back on the sling to a distance of 10 centimeters, release the sling, and record the distance the marble travels.
Step 3 Place the marble in the slingshot, pull back on the sling to a distance of 5 centimeters, release the sling, and record the distance the marble travels.
What will MOST LIKELY be the result of this investigation?

A.
The marble released from a distance of 5 centimeters will have the most potential energy transferred into kinetic energy, causing the marble to travel the farthest.

B.
The marble released from a distance of 15 centimeters will have the most potential energy transferred into kinetic energy, causing the marble to travel the farthest.

C.
The marble released from a distance of 5 centimeters will have the least potential energy transferred into kinetic energy, causing the marble to travel the farthest.

D.
The marble released from a distance of 15 centimeters will have the least potential energy transferred into kinetic energy, causing the marble to travel the farthest.

Answer 3

B. The marble released from a distance of 15 centimeters will have the most potential energy transferred into kinetic energy, causing the marble to travel the farthest.
