Simple harmonic motion Question and answer 1
what is damped oscillation?
Answer: Damped oscillation is one in which the amplitude gradually decrease with time and finally come to stop or zero.
Simple harmonic motion Question and answer 2
Is a body moving with constant speed in a circular path undergoing acceleration?
Answer: No it not undergoing acceleration, because the association is rate of change velocity but here the velocity is constant
Simple harmonic motion Question and answer 3
A 10kg mass is suspended from the end of a spring and released. If the spring oscillates in simple harmonic motion with a speed of 0.5s, find the energy given to the 10 kg mass if the amplitude of the oscillation is 2cm.
Answer: solution, using
Where m=mass suspended and k= elastic constant
Squaring the both side we have
For energy use
where x = the amplitude=2cm=0.02m
Simple harmonic motion Question and answer 4
3. State the formula used in calculating period in simple pendulum and in loaded spiral spring performing simple harmonic oscillation
Simple harmonic motion Question and answer 5
what is the condition of acceleration of body performing simple harmonic motion?
Answer: Acceleration of a body performing simple harmonic motion is directed toward the fixed point and proportional to the distance from the fixed point.
Simple harmonic motion Question and answer 6
The period of a simple pendulum x is 1.5s. What is the period of a simple pendulum y which makes 500 vibration in the time it takes x to make 400 vibrations?
Answer: 1.5s = 400 vibration
?s = 500 vibration , this implies that
Simple harmonic motion Question and answer 7
What is resonance?
Answer: Resonance is a phenomenon which occurs whenever a particular body or a system is set to oscillation at its own natural frequency as a result of impulses or signals received from some other system or body which is vibrating with the same frequency
Simple harmonic motion Question and answer 8
What is the relationship between period and frequency?
Answer: the relationship is that the period is reciprocal of frequency, that is
T =1/F or F=1/T
Simple harmonic motion Question and answer 9
Name one example of resonance
Answer: A rattling windows when a aeroplane passes overhead
