L 11-1 simple harmonic motion spring oscillation Flashcards
1
Q
Periodic Motion
A
each cycle repeats itself identically at a constant time
2
Q
cycle
A
oscillation
3
Q
period ( T )
A
time in seconds it takes for one cycle to complete
S.I unit: seconds (s)
4
Q
Frequency ( f )
A
number of cycles or oscillations per second
S.I unit: hertz (Hz)
5
Q
Amplitude
A
the maximum displacement (distance) from rest position (equilibrium)
S.I unit: meter (m)
6
Q
Oscillation
A
the repeated back and forth movement of something between two positions or states.
7
Q
when does a simple harmonic motion (SHM) occur?
A
a particle or object moves back and forth within a stable equilibrium position under the influence of a
restoring force proportional to its displacement
8
Q
F
A
restoring force. S.I unit is N
9
Q
K:
A
spring constant . S.I unit is N/m
10
Q
X:
A
displacement from equilibrium. S.I unit is m
