Q1Domain Verified
According to "The Complete IB Physics IA Course 2026", when designing an experiment to investigate the relationship between the frequency of a simple pendulum and its period, which of the following is NOT a crucial consideration for achieving a robust investigation?
D) Utilizing a consistent and stable suspension point for the pendulum to minimize extraneous rotational effects.
Ensuring the amplitude of oscillation remains small (typically less than 10 degrees) to approximate simple harmonic motion.
Precisely measuring the period of oscillation for a sufficient number of trials to calculate a reliable average.
Controlling the mass of the pendulum bob to isolate the effect of frequency on the perio
Q2Domain Verified
In the context of "The Complete IB Physics IA Course 2026", when a student is analyzing experimental data for their physics IA and encounters a systematic error that has led to a consistently higher set of measured values, what is the most appropriate course of action for a specialist-level analysis?
Apply a simple mathematical correction to all data points based on the magnitude of the suspected error.
Clearly identify and explain the source of the systematic error in the report and discuss its impact on the results, potentially re-analyzing the data with a corrected model if feasible.
Discard all data points that deviate significantly from the expected trend.
Focus solely on calculating the percentage error for the remaining data points to demonstrate an understanding of uncertainty.
Q3Domain Verified
According to "The Complete IB Physics IA Course 2026", when evaluating the uncertainty in a derived quantity in a physics IA, such as the kinetic energy calculated from measured mass and velocity, what is the most accurate and specialist method to determine the overall uncertainty?
Summing the absolute uncertainties of the individual measurements.
Using the largest fractional uncertainty among the individual measurements as the uncertainty for the derived quantity.
Taking the square root of the sum of the squares of the fractional uncertainties of the individual measurements, multiplied by the derived quantity.
Averaging the percentage uncertainties of the individual measurements.
