Simple Harmonic Motion (SHM)

At mean position, which quantity is maximum?
Answer: Velocity
At extreme position, which quantity is zero?
Answer: Velocity
At which position is acceleration maximum?
Answer: Extreme position
The ratio of kinetic to potential energy at x = A/2 is:
Answer: 3 : 1
If total energy is E, kinetic energy at x = A/√2 is:
Answer: E/2
When displacement is negative, restoring force is:
Answer: Positive
In one oscillation, acceleration is maximum how many times?
Answer: Twice
Which quantity changes sign at mean position?
Answer: Acceleration
The particle spends maximum time near:
Answer: Extreme positions
Which graph is a straight line?
Answer: Acceleration vs displacement
If amplitude doubles, maximum kinetic energy becomes:
Answer: Four times
Which remains constant throughout SHM?
Answer: Angular frequency
At what displacement is speed half of maximum?
Answer: x = (√3/2)A
Which pair is always opposite in direction?
Answer: Displacement and acceleration
The time period does NOT depend on:
Answer: Amplitude
Total energy is proportional to:
Answer: A²
Which quantity is zero only once in one cycle?
Answer: Displacement
The motion is fastest when:
Answer: Passing through mean position
If x = A sin(ωt), velocity is:
Answer: Aω cos(ωt)
Which method is safest for JEE?
Answer: Energy + symmetry

JEE ADVANCED TRAP:
Do NOT assume “maximum” always means “mean position”. Acceleration is maximum at extremes — velocity is not.
