Further Mechanics

State the condition for simple harmonic motion.

Acceleration is directly proportional to the negative of displacement.

What is underdamping?

The amplitude of the oscillation decreases gradually and the system will continue to oscillate for a long time.

State the condition for simple harmonic motion.

Acceleration is directly proportional to the negative of displacement.

What is underdamping?

The amplitude of the oscillation decreases gradually and the system will continue to oscillate for a long time.

What is critical damping?

It reduces the amplitude in the shortest possible time.

What is overdamping?

Prevents system from oscillating and returns to equilibrium very slowly.

What is circular motion?

Movement of an object along the circumference of a circle.

What is simple harmonic motion?

Vibration about an equilibrium position in which a restoring force is proportional to the displacement from equilibrium.

Define forced vibrations

A driving force causes the system to vibrate at a different frequency.

Define free vibrations

System vibrates at it's natural frequency

Define resonance

A system's amplitude of oscillation increases significantly when the frequency of an external force matches its natural frequency.

State the necessary conditions for SHM

Acceleration is proportional to displacement and in the opposite direction.
