Oscillations Flashcards
1
Q
Simple harmonic motion
A
Motion where acceleration of particle is proportional to but in the opposite direction to displacement of particle
2
Q
Equilibrium position
A
When connecting spring is neither stressed/compressed
3
Q
Oscillation
A
Movement of particle from position back to its original position
4
Q
Restoring force
A
Pushing “block” back to equilibrium position
5
Q
Elastic potential energy
A
Stored in stretched/compressed spring & is transformed into KE (& back again)
6
Q
Period
A
Time taken to complete an oscillation
7
Q
Frequency
A
Number of cycles completed per second
8
Q
Simple pendulum
A
Consists of weight of mass attached to a massless rod that swings without friction about vertical equilibrium force
