Understanding the Foucault Pendulum

What is the primary purpose of the Foucault pendulum experiment?

• To calculate gravitational force

• To demonstrate the Earth's rotation

• To observe the effects of magnetism

• To measure the speed of light

Why is it challenging to visualize the pendulum's motion in a video?

• The pendulum is too small to see

• The pendulum's motion is too slow

• The pendulum's path is unpredictable

• The pendulum moves too quickly

What role does the electromagnet play in the pendulum setup?

• It keeps the pendulum swinging

• It measures the pendulum's speed

• It changes the pendulum's direction

• It stops the pendulum from swinging

How did the narrator ensure the camera captured the pendulum at the right moment?

• By programming an electronic setup

• By using a high-speed camera

• By manually taking photos

• By using a stopwatch

What was the unexpected outcome after 28 hours of observation?

• The pendulum completed its cycle early

• The pendulum's weight increased

• The pendulum stopped swinging

• The pendulum changed direction
