Question

Three different experiments are conducted that pertain to the oscillatory motion of a pendulum. For each experiment, the length of the pendulum and the mass of the pendulum are indicated. In all experiments, the pendulum is released from the same angle with respect to the vertical. If the students collect data about the kinetic energy of the pendulum as a function of time for each experiment, which of the following claims is true?
a. The data collected from Experiment 1 will be the same as the data collected from Experiment 2.
b. The data collected from Experiment 1 will be the same as the data collected from Experiment 3.
c. The data collected from Experiment 2 will be the same as the data collected from Experiment 3.
d. The data collected from each experiment will be different.

Answer 1

Answer:

d. The data collected from each experiment will be different.

Explanation:

The time period of simple pendulum depends on length of pendulum and independent of mass of pendulum.

For three experiments data is collected. Kinetic energy depends on mass and square of velocity.

SO FOR THREE EXPERIMENTS THE DATA COLLECTED WILL BE DIFFERENT.
