Pendulum Motion and Time Periods

The video tutorial explains the concept of a pendulum, which is a weight suspended from a pivot that swings freely, demonstrating oscillatory motion. It describes how to calculate the time period of a pendulum by measuring the time taken for 10 oscillations. The tutorial further explores how shortening the pendulum affects its time period, showing that a shorter pendulum has a shorter time period. The key takeaway is that the time period of a pendulum depends on its length.

What is the motion called when a pendulum swings back and forth?

• Linear motion

• Oscillatory motion

• Circular motion

• Random motion

What is the term used for the time taken by a pendulum to complete one full swing?

• Velocity

• Amplitude

• Frequency

• Time period

How long did it take for the pendulum to complete 10 oscillations in the first measurement?

• 13 seconds

• 10 seconds

• 8.5 seconds

• 15 seconds

What is the time period of the pendulum when it took 13 seconds for 10 oscillations?

• 1.5 seconds

• 1.3 seconds

• 1.0 seconds

• 1.8 seconds

What happens to the time period when the length of the pendulum is shortened?

• It increases

• It remains the same

• It becomes zero

• It decreases

How long did it take for the shorter pendulum to complete 10 oscillations?

• 13 seconds

• 15 seconds

• 8.5 seconds
