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.
