OSCILLATIONS

OSCILLATIONS

1. Periodic motion

   • motions that repeat its conditions or its state of motion.

2. Period (T)

   • is the time it takes an object to complete one revolution around its circular path.
   • (T)
     • second (s)

3. Frequency (f)

   • number of times which the process repeats its conditions in a period of time.
   • (f)
     • Hertz, 1/s

4. Oscillator motion

   • repeated motion in which an object repeats the same movement over and over.
   • Restoring force
     • force that makes an object to oscillate.

5. Simple harmonic motion

   • periodic motion produced by a restoring force that is directly proportional to the displacement with opposite direction, it is frctionless.

6. Motion amplitude

   • the distance from the centre of motion to either extreme.

7. Simple Pendulum

   • is one which can be considered to be a point mass suspended from a string or rod of negligible mass.

8. Hooke's Law

   • the force needed to extend or compress a spring by some distance is proportional to that distance.
     • F= -kx
