Understanding Six Marker Questions in Physics

What is the first step in approaching a six marker question according to the video?

• Discuss with a peer before answering.

• Look at the answer key for guidance.

• Read the question carefully and underline key information.

• Start writing the answer immediately.

In the experimental setup, why is a long tube used?

• To allow more light gates to be used.

• To make the experiment look more impressive.

• To increase the difficulty of the experiment.

• To ensure the sphere reaches terminal velocity.

What is the purpose of using light gates in the experiment?

• To measure the time taken for the sphere to pass through.

• To calculate the density of the liquid.

• To determine the color of the sphere.

• To measure the diameter of the sphere.

Which instrument is recommended for measuring the diameter of the sphere?

• Thermometer

• Protractor

• Micrometer

• Ruler

Why is it important to take multiple measurements and find the average?

• To increase the complexity of the experiment.

• To minimize random errors.

• To make the experiment more time-consuming.

• To confuse the examiner.

What is plotted on the x-axis when analyzing the data to find the constant k?

• Terminal velocity (v)

• Radius squared (r²)

• Time (t)

• Radius (r)

What indicates that the relationship between variables is correct in the graph?

• The graph has multiple peaks.

• The graph is a curved line.

• The graph is a horizontal line.

• The graph is a straight line through the origin.

What does the gradient of the graph represent in this experiment?

• The diameter of the sphere.

• The radius of the sphere.

• The constant k.

• The time taken.

What safety precaution is mentioned for securing the experimental setup?

• Using a fire extinguisher.

• Wearing safety goggles.

• Ensuring the room is well-lit.

• Using a secured clamp stand.

What is the final step in ensuring all requirements of the six marker question are met?

• Discussing the answer with a friend.

• Rewriting the question.

• Checking that all parts of the question have been addressed.

• Adding more diagrams.
