Demonstrating What Changes the Period of Simple Harmonic Motion

The video tutorial explains the concept of period in physics, focusing on simple harmonic motion. It covers the units of period, the pattern of motion, and the equations for calculating periods in mass spring systems and pendulums. The tutorial also discusses factors affecting periods, such as mass, spring constant, and gravity, and clarifies that amplitude does not affect the period in simple harmonic motion. The video concludes by highlighting the conditions under which a pendulum remains in simple harmonic motion.

If an object starts at position one in simple harmonic motion, what sequence does it follow to complete one full cycle?

• 1-3-1-2

• 1-2-1-3

• 1-3-2-1

• 1-2-3-2-1

What is the formula for the period of a mass-spring system?

• 2π times the square root of gravity divided by pendulum length

• 2π times the square root of the pendulum length divided by gravity

• 2π times the square root of the mass divided by spring constant

• 2π times the square root of the spring constant divided by mass

Which factor does not affect the period of a simple pendulum?

• Mass of the pendulum bob

• Amplitude

• Acceleration due to gravity

• Pendulum length

What happens to the period of a mass-spring system if the mass is increased?

• The period becomes zero

• The period increases

• The period remains the same

• The period decreases

How does increasing the spring constant affect the period of a mass-spring system?

• It decreases the period

• It increases the period

• It has no effect on the period

• It doubles the period

What is the effect of increasing the pendulum length on its period?

• The period becomes zero

• The period increases

• The period remains unchanged

• The period decreases

Why does a pendulum with an amplitude greater than 15 degrees not follow simple harmonic motion?

• The pendulum stops moving

• The motion is no longer periodic

• The period equation for simple harmonic motion no longer applies

• The period becomes infinite
