Question

When do you use Harmonic motion or Damped Harmonic motion?

Answer 1

Anything that oscillates. Waves, things attached to springs, things bobbing up and down in the water.

Answer 2

Damped harmonic motion is a more sophisticated model that takes into account friction of some kind.

Answer 3

What animal said. =)
If you don't use damped harmonic motion, then you're assuming the motion never slows down or gets any smaller.

Answer 4

Ok so use Harmonic motion if there is no friction or some sort mentioned in the question yes?

Answer 5

Correct.

Answer 6

Right.

Answer 7

cool thanks

Answer 8

My pleasure! =D

Answer 9

what about use either sine or cosine?
