Question

1. How would the motion of a pendulum change at high altitude like a high mountain top? How would the motion change under weightless conditions?

Answer 1

Answer:

A pendulum moves with the principle of small angles that show that the frequency and period of the pendulum are not dependent on the initial angular displacement of the mass it carries.

On a high mountain top, a reduced force of gravity is exerted on the mass, therefore, producing long periods of oscillation on the pendulum.

However, under weightless conditions where gravity is zero, the pendulum will not work as what keeps the mass in oscillation is gravity. If therefore gravity is absent there can be no oscillation.
