A particle performing SHM with a frequency 10 hearts and amplitude 5 c...
Explanation of SHM with given parameters
Defining SHM
Simple Harmonic Motion (SHM) is the motion of an object back and forth around its mean position under the influence of a restoring force that is directly proportional to the displacement from the mean position.
Frequency and Amplitude
- The frequency of SHM is the number of oscillations per second and is denoted by 'f'.
- Here, the frequency is given as 10 Hz.
- The amplitude of SHM is the maximum displacement of the particle from its mean position and is denoted by 'A'.
- Here, the amplitude is given as 5 cm.
Displacement of the particle
The displacement of the particle at any time 't' can be given by the equation:
x = A cos(2πft)
where,
x = displacement of the particle
A = amplitude of SHM
f = frequency of SHM
t = time
In this case, the particle is initially in left extreme position, which means its displacement is maximum and negative. Therefore, we can write:
x = -5 cos(2π10t)
Visualization of displacement
As the particle is performing SHM, its displacement will keep changing with time. The displacement-time graph of the particle will be a sinusoidal wave with a frequency of 10 Hz and an amplitude of 5 cm. The particle will move back and forth around its mean position, crossing the mean position twice in each cycle.
Conclusion
In conclusion, the displacement of the particle performing SHM with a frequency of 10 Hz and an amplitude of 5 cm initially in left extreme position can be given by the equation x = -5 cos(2π10t). The particle will move back and forth around its mean position, crossing the mean position twice in each cycle.
