Question

2 Two students are measuring the acceleration due to gravity g using a simple pendulum.Student A measures the value as 8.9 ms-² and Student B measures the value as 5 ms-² a) State two possible errors in student B's experiment.​

Answer 1

Two possible errors in Student B's pendulum experiment that resulted in a low acceleration due to gravity measurement could include an incorrect measurement of the pendulum's period and an insufficient or inaccurately measured length of the pendulum.

Step-by-step explanation:

The question refers to the measurement of the acceleration due to gravity using a simple pendulum. Since Student B measured the value of gravity as 5 ms², which is significantly lower than the standard value of approximately 9.8 ms², two possible errors could be:

• Incorrect measurement of the pendulum's period: The value of gravity is highly sensitive to the period of oscillation, so an inaccurately measured time period could result in a significantly erroneous value of g.
• Insufficient length of the pendulum: If the pendulum's length was not measured correctly or was too short, the period of oscillation could be affected, leading to a lower calculation of gravity.

It is essential to ensure accurate timekeeping and precise length measurement when using a pendulum to measure gravity.
