C.1 Simple Harmonic Motion

Question 1

Oscillation

Answer 1

Back and forth motion about an equilibrium position

Question 2

Isochronous

Answer 2

When an oscillation repeats with the same time period

Question 3

Displacement (x)

Answer 3

Instantaneous distance from the equilibrium position in a specific direction (m)

Question 4

Amplitude (xo)

Answer 4

Maximum displacement from the equilibrium position (m)

Question 5

Frequency (f)

Answer 5

Number of oscillations per second (Hz or s-1)

Question 6

Period (T)

Answer 6

Time for one oscillation (s)

Question 7

Phase (o)

Answer 7

Measure of how in step different particles are

Question 8

Simple harmonic motion

Answer 8

Oscillation that takes place when the acceleration of and the force on an object are proportional to the displacement from equilibrium position and in the opposite direction to the displacement

Question 9

What is simple harmonic motion due to?

Answer 9

A restoring force

Question 10

Angular frequency (w)

Answer 10

Angular speed that an object undergoing circular motion would have if it were to match the SHM (rads-1)

Question 11

Straight line of acceleration-displacement graph

Answer 11

Acceleration is proportional to displacement

Question 12

Negative gradient of acceleration-displacement graph

Answer 12

Acceleration and displacement are in opposite directions
