IB Physics HL S2.1.2 Designing Investigations Questions question 1
[Maximum number: 1]
A student wants to verify the relation T=2πgL between the period T of a simple pendulum and the length L of the pendulum, where g is the acceleration of free fall. The student operates a stopwatch to measure one oscillation and a millimeter ruler to measure the length of the pendulum.
State, for this experiment,
one variable that must be controlled,
mass OR diameter OR material of bob OR « initial » amplitude/angle
Marking guidance:
Do not allow statements about rulers, stopwatches, string, number of oscillations, constant gravity.
