Physics QUARTER FOUR ASSESSMENT 1112
Today you will be taking the physics quarter four assessment. This test is designed
to test your skills and knowledge in science. It has questions taken from science
classes, as well as about experiments. You should make sure to read each question
carefully, including the information given at the beginning of each section. Examine
the diagrams to help you understand the questions as well. Some questions may
refer to diagrams or information from the previous page.
For the multiple choice sections, make sure to place your answers on your
Scantron sheet. Make sure the Scantron has your full name, neatly written, as well
as your student ID. For the open ended questions, make sure to read all the
information, and write your answer clearly in the space provided

Use the information on the next pages to answer the four open-ended
experimentation questions. Answer the questions in the space provided. Make sure
to write clearly and neatly, while answering the question fully. Remember to
answer the question, then WRITE a good explanation. You can always add
diagrams or charts if you think it will help explain your answer.
A group of students wanted to answer the question: What factors affect how a pendulum swings?
They tested the effect of mass and angle (how far back it was pulled). One group, Kim, Marie
and Rick changed the mass. They took turns timing how long it took for ten swings, and how
long it took to stop completely
The table below shows their results:
