Exam 20: Principles of Oscillatory Motion and Related Measurements

For a resonating system it should oscillate

If the swing moves from right to left, then velocity is

Oscillatory motion has a

A train with a whistle that emits a note of frequency 800 Hz is approaching an observer at speed of 60 m s^-1, the frequency of note heard by observer is {{}}

angular frequency of s.h.m is equal to

Acceleration is directly related to

Number of oscillations per unit time is

Oscillations become damped due to

If an object moves back and forth repeatedly around a mean position it is called

If the two quantizes are inversely proportional then graph between y and 1/x gives

Systematic errors occur due to

Systematic errors can be removed by

In cells, internal resistance is due to

Velocity at equilibrium position is

Gradient of velocity-time graph gives

Terminal potential difference of battery depends on

In s.h.m, object's acceleration depends upon

In s.h.m, acceleration is always directed towards the

Smallest division on a rule is of

Magnitude of gradient of a-x graph is {{}}
