## Learning Exercise: 1D Motion Physlet Problem #1

Title:
1D Motion Physlet Problem #1
Material:
Description:
Adaptation of Mario Belloni's physlet problem to work as a calculated question within WebCT.
Course: Introductory physics.

### Exercise

Mario's orgininal problem may be viewed at

http://webphysics.davidson.edu/physletprob/ch8_problems/ch8_1_kinematics/kinematics_1.html
.
It involves two blocks with different motion parameters. A green block
accelerates from rest, and an orange block moves at constant velocity.
Both blocks start from the same point at t=0. The questions asks for the
point at which the green block overtakes the orange block. The animation
stops before this event occurs.

The modification utilizes the random parameter feature of the WebCT
calculated question format. The advantage here is that you can allow unlimited
attempts and encourage collaboration. Since the parameters are
re-randomized on each attempt, it is appropriate to report the correct answer after an incorrect submission.

The WebCT version of this question is at

http://webhw.unca.edu/bennett/WebCT/physlet_1d_1.zip
.
Download and unzip the file, and import into WebCT. A question database
category will be created called physlet_problems (if it does not already
exist).

Once you have the problem working, create a quiz that uses it. The quiz
settings that I find most effective for this problem are

• Unlimited attempts

• Highest score determines grade

• Release the score once the quiz has been submitted

• Show the student's response for each question

• Show the correct answer for each question
