Measuring SHM

Front

What is Simple Harmonic Motion (SHM)?

Back

Simple Harmonic Motion (SHM) is a type of periodic motion where an object moves 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.

Front

What happens to the restoring force at the equilibrium position in SHM?

Back

At the equilibrium position, the restoring force is at a minimum (zero), meaning the object experiences no net force.

Front

How does mass affect the period of a simple pendulum?

Back

The mass of a simple pendulum does not affect its period; two pendulums of the same length will have the same period regardless of their masses.

Front

What is the relationship between displacement and acceleration in SHM?

Back

In SHM, the acceleration is directly proportional to the displacement from the equilibrium position and is directed towards it, following the formula a = -ω²x.

Front

What is the maximum displacement in SHM called?

Back

The maximum displacement in SHM is called the amplitude (A).

Front

What is the significance of the negative sign in the acceleration formula a = -ω²x?

Back

The negative sign indicates that the acceleration is always directed towards the equilibrium position, opposing the displacement.

Front

What is the phase of an object in SHM?

Back

The phase of an object in SHM describes its position in the cycle of motion at a specific time, often expressed in radians.

Front

What is the relationship between frequency and period in SHM?

Back

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

Front

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

Back

Increasing the length of a pendulum increases its period; a longer pendulum swings more slowly.
