SHM

When does the mass move at maximum velocity in a mass-spring system?

• At equilibrium

• At the farthest point from the equilibrium

• At its hightest point

• At its lowest point

The period of a pendulum may be decreased by

• shortening its length.

• increasing the mass of the bob

• moving its equilibrium point

• decreasing the mass of the bob

A pineapple is experiencing SHM, vertically. Which part of its displacement phasor will give its actual displacement from equilibrium?

• its angular frequency

• its acceleration

• its vertical component

• its horizontal component

A mass is oscillating horizontally on a spring in SHM. The diagram shows its reference circle. What aspect of its displacement phasor gives the linear displacement of the mass?

• Its angular frequency

• its vertical component

• its overall length

• its horizontal component

If an object is in oscillatory motion, what must be true if it's in simple harmonic motion? 

• Its motion is along the path of a circle

• acceleration is proportional to the displacement

• Its potential energy is equal to the kinetic energy

• It's attached to a spring
