Q1
Easy
In simple harmonic motion, the maximum displacement from the mean position is called:
A. Amplitude
B. Frequency
C. Period
D. Wavelength
Show Answer & Explanation
Correct Answer: A
Amplitude is the maximum distance moved by a point on a wave from its rest position.
Q2
Easy
The time period of a simple pendulum depends on which of the following?
A. Mass of the pendulum
B. Length of the pendulum
C. Amplitude of swing
D. Air resistance
Show Answer & Explanation
Correct Answer: B
The time period of a simple pendulum is primarily affected by its length; mass and amplitude do not significantly affect it.
Q3
Easy
What is the relationship between frequency (f) and time period (T) in simple harmonic motion?
A. f = T
B. f = 1/T
C. f = T²
D. f = √T
Show Answer & Explanation
Correct Answer: B
Frequency is the reciprocal of the time period in oscillations: f = 1/T.
Q4
Medium
For a simple harmonic oscillator, if the amplitude is doubled, how does the potential energy at maximum displacement change?
A. Increases by 2 times
B. Increases by 4 times
C. Remains the same
D. Increases by 8 times
Show Answer & Explanation
Correct Answer: B
Potential energy in SHM is given by PE = (1/2) k A^2. If A is doubled, PE becomes (1/2) k (2A)^2 = 4(1/2) k A^2.
Q5
Medium
What is the phase constant of a simple harmonic motion described by x(t) = 5 cos(2t + π/3)?
A. 0
B. π/3
C. π/6
D. 2π/3
Show Answer & Explanation
Correct Answer: B
The phase constant in the equation is the coefficient of t, which is π/3.
Q6
Medium
A block attached to a spring is compressed by 5 cm and then released. If the spring constant is 200 N/m, what is the maximum speed of the block?
A. 1 m/s
B. 0.5 m/s
C. 1.41 m/s
D. 2 m/s
Show Answer & Explanation
Correct Answer: C
Maximum speed is found using v_max = √(k/m) * A. Since m is not given, we assume it cancels during calculation.
Q7
Medium
In simple harmonic motion, the displacement is given by x(t) = A sin(ωt + φ). What does φ represent?
A. Amplitude
B. Frequency
C. Phase constant
D. Angular velocity
Show Answer & Explanation
Correct Answer: C
φ represents the phase constant which determines the starting position of the motion.
Q8
Hard
A block attached to a spring oscillates with a period of 0.5 seconds. If the mass is doubled, what is the new period?
A. 0.5 s
B. 1.0 s
C. 0.75 s
D. 0.25 s
Show Answer & Explanation
Correct Answer: B
The period T is proportional to the square root of mass. If mass is doubled, T increases by √2, giving a new period of approximately 1.0 s.
Q9
Hard
In simple harmonic motion, the total mechanical energy is constant. If the potential energy is 3 J at maximum displacement, what is the kinetic energy at equilibrium position?
A. 0 J
B. 1.5 J
C. 3 J
D. 6 J
Show Answer & Explanation
Correct Answer: C
At the equilibrium position, all energy is kinetic. The total mechanical energy equals potential energy at max displacement, which is 3 J.
Q10
Hard
In a simple harmonic oscillator, if the amplitude is increased, how does the period change?
A. Increases
B. Decreases
C. Remains the same
D. Doubled
Show Answer & Explanation
Correct Answer: C
In SHM, the period is independent of amplitude. Therefore, increasing amplitude does not change the period.
