SHM & Damping

The greatest distance an object moves from equilibrium position during SHM

• Displacement
• Amplitude
• Height
• Zenith

The force required to stretch or compress a spring by 1 metre

• Spring force
• Constant length
• Inertia
• Spring Constant

Any effect causing a loss of energy during SHM

• Absorption
• Damping
• Decay
• Drying

Middle position of SHM

• Amplitude
• Angular displacement
• central maximum
• Orthocentre

Motion when a varying force is used to drive an oscillating system

• Reverberation
• Over damping
• Forced oscillation
• Natural frequency

Repeated over and over again at regular intervals

• constant
• cyclical
• periodic
• rhythmic

A time-based vector

• circle
• cycle
• phasor
• vector

An imaginary circle around an object performing SHM

• reference circle
• phasor
• orbit
• halo

When the frequency of a forced SHM matches the natural frequency, resulting in a large amplitude

• damping
• exponential growth
• phasing
• resonance

A repeated motion where the acceleration is proportional to the displacement and directed towards the equilibrium position

• A = kx
• a=-k y
• f=mv2/r
• T=Fr
