Simple Harmonic Motion

Front

What is Simple Harmonic Motion (SHM)?

Back

Simple Harmonic Motion 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 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.

Define frequency in the context of SHM.

Back

Frequency is the number of complete cycles or vibrations that occur in a unit of time, typically measured in Hertz (Hz).

Front

What is the relationship between period and frequency?

Back

The period (T) and frequency (f) are inversely related: T = 1/f.

Front

What is amplitude in SHM?

Back

Amplitude is the maximum displacement of an object from its equilibrium position during oscillation.

Front

How does the length of a pendulum affect its period?

Back

The period of a pendulum increases with the length; a longer pendulum has a longer period.

Front

What is the formula for the velocity of a mass-spring system in SHM?

Back

The velocity (v) of a mass-spring system in SHM can be expressed as v(t) = Aω cos(ωt + φ), where A is the amplitude, ω is the angular frequency, and φ is the phase constant.

Front

What is the angular frequency in SHM?

Back

Angular frequency (ω) is the rate of change of the phase of a sinusoidal waveform, measured in radians per second, and is related to frequency by ω = 2πf.

Front

What is the restoring force in SHM?

Back

The restoring force is the force that brings the object back towards its equilibrium position, proportional to the displacement from that position.

Front

What is the significance of the equilibrium position in SHM?

Back

The equilibrium position is the point where the net force acting on the object is zero, and it is the central point around which the oscillation occurs.
