2016 #5 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers question #5 from the 2016 AP Physics One exam, focusing on a problem involving a standing wave on a rope. It explains why the tension at point P is greater than at point Q due to the mass below each point. The tutorial also discusses a hypothesis that increasing tension in a rope increases wave speed, supported by the relationship between wave speed, wavelength, and frequency. The video concludes with scoring guidelines and emphasizes the importance of structured responses.

What happens to the rope when the oscillator is turned on at a certain frequency?

• The rope oscillates randomly.

• The rope breaks due to tension.

• The rope forms a standing wave.

• The rope remains still.

Why is the tension at point P greater than at point Q on the rope?

• Point P has more mass below it.

• Point Q is at a higher elevation.

• Point Q has more mass below it.

• Point P is closer to the oscillator.

What is the relationship between the force of tension and the force of gravity on the rope?

• They are unrelated forces.

• Tension is always greater than gravity.

• They are equal in magnitude.

• Gravity is always greater than tension.

How does increasing tension in the rope affect wave speed?

• Wave speed increases.

• Wave speed remains constant.

• Wave speed becomes unpredictable.

• Wave speed decreases.

What is the significance of paragraph structure in the response to Part B?

• It is not important.

• It helps in gaining additional points.

• It makes the response longer.

• It confuses the reader.
