Simple Harmonic Motion

Front

What is Simple Harmonic Motion (SHM)?

Back

Simple Harmonic Motion (SHM) is a type of periodic motion where an object oscillates back and forth around an equilibrium position, with a restoring force proportional to the displacement from that position.

What is the formula for the period (T) of a simple pendulum?

Back

The period (T) of a simple pendulum is given by the formula T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

Front

How does the length of a pendulum affect its period?

Back

The period of a pendulum increases with increasing length; shortening the length decreases the period.

Front

What is the relationship between frequency (f) and period (T)?

Back

Frequency (f) is the reciprocal of the period (T), given by the formula f = 1/T.

Front

What is the frequency of a simple harmonic oscillator that takes 4.8 seconds to complete 5 vibrations?

Back

The frequency is 1.04 Hz, calculated as f = number of cycles / time = 5 / 4.8.

Front

What does the term 'equilibrium position' refer to in the context of SHM?

Back

The equilibrium position is the point at which the net force acting on the oscillating body is zero, and it would come to rest if it lost all its energy.

Front

What is the significance of the restoring force in SHM?

Back

The restoring force is crucial in SHM as it acts to bring the object back to its equilibrium position, and it is proportional to the displacement from that position.

Front

What is the effect of damping on simple harmonic motion?

Back

Damping reduces the amplitude of oscillations over time, eventually leading to the cessation of motion.

Front

What is the maximum displacement from the equilibrium position called?

Back

The maximum displacement from the equilibrium position is called the amplitude.

Front

How does gravity affect the period of a pendulum on different planets?

Back

The period of a pendulum is affected by the gravitational acceleration (g); a higher g results in a shorter period, while a lower g results in a longer period.
