Simple Harmonic Motion Concepts

The video tutorial covers simple harmonic motion, explaining its properties such as periodicity, equilibrium, and restoring force. It defines key terms like period, frequency, and amplitude, and analyzes graphs of position, velocity, and acceleration. The tutorial also discusses types of oscillators, including pendulums and springs, and explores energy transformations within these systems.

Which of the following is a characteristic of simple harmonic motion?

• The force acts away from the equilibrium position.

• The motion is random.

• The restoring force decreases with distance.

• The motion is periodic.

What is the relationship between period and frequency in simple harmonic motion?

• They are both measured in seconds.

• They are unrelated.

• They are inverses of each other.

• They are directly proportional.

What does the amplitude represent in simple harmonic motion?

• The number of oscillations per second.

• The speed of the object at equilibrium.

• The maximum distance from the equilibrium position.

• The time for one complete cycle.

In the equation x = A cos(2πft), what does 'A' represent?

• Period

• Frequency

• Velocity

• Amplitude

What happens to the velocity of a simple harmonic oscillator at maximum displacement?

• It is zero.

• It is equal to the acceleration.

• It is negative.

• It is at its maximum.

Which factor affects the period of a simple pendulum?

• Color of the pendulum

• Mass of the pendulum

• Length of the pendulum

• Amplitude of oscillation

According to Hook's Law, what happens when a spring is stretched twice as far?

• The force required is halved.

• The force required is doubled.

• The force required remains the same.

• The spring constant changes.

What is the role of the spring constant in a mass-spring system?

• It determines the mass of the spring.

• It measures the length of the spring.

• It is irrelevant to the system.

• It affects the period of oscillation.

At what point is the kinetic energy of a simple harmonic oscillator at its maximum?

• At the lowest point

• At the highest point

• At the equilibrium position

• At maximum displacement

What remains constant in a simple harmonic oscillator?

• Total energy

• Kinetic energy

• Potential energy

• Velocity
