Unit 6: Simple Harmonic MotionWhat is Simple Harmonic Motion?-✔Simple Harmonic Motion is a type of
periodic motion where the restoring force is directly proportional to the
displacement from the equilibrium position and is directed towards it.
Is SHM periodic and repetitive?-✔Yes, SHM is periodic and repetitive.
What is the relationship between acceleration and displacement in
SHM?-✔The acceleration is directly proportional to the displacement and is
always directed towards the equilibrium position.
When is the velocity maximum in SHM?-✔The velocity is maximum at the
equilibrium position and minimum at the extreme positions.
Are displacement, velocity, and acceleration sinusoidal functions of time in
SHM?-✔Yes, the displacement, velocity, and acceleration are all sinusoidal
functions of time in SHM.
Is the period of oscillation dependent on the amplitude in SHM?-✔No, the
period of oscillation is independent of the amplitude in SHM.
What are some examples of SHM?-✔Examples of SHM include a mass
attached to a spring and oscillating vertically or a pendulum swinging back
and forth.
What is the displacement equation in SHM?-✔Displacement: x = A cos(ωt
+ φ), where A is the amplitude, ω is the angular frequency, t is the time,
and φ is the phase angle.
What is the velocity equation in SHM?-✔Velocity: v = -Aω sin(ωt + φ),
where A is the amplitude, ω is the angular frequency, t is the time, and φ is
the phase angle.
