Lesson 3 - Oscillations

Question 1

Quick notes

Answer 1

mechanical and translational oscillation today.
forced oscillation in heartbrat and gunga.

frequency and period are opposite, inverse values. 2 oscillations by 1 second = 2 hertz

period is not same. 2 oscillation per 1 second. half!

spring pendulum, difference in different angles.

A= 6 cm. from equil 6 cm.
angular frequency= w=2pi/T

units in presentation.

in medicine eg. Inverse pendel. oscillating around equilibrium.
Respiratory rate and heartbeat, vocal cords are oscillation. All proccesses that repeat are oscillations.
use final formulas in labwork.
L to G but since G is constant only L affects. Mass does NOT affect period!!!

Spring pendulum DEPENDS on the mass.
period calcl. formulas in presentation
relative error: how svcattered data are, based on random errors.
More careful –> better precsion.

Accuracy defined by how well calibrated device is. Could be precise nbut far away from theoretical value.
could see how close our g is to our refrence value = see how accurate our measurements are

full oscillation

Delta 1
3s - 2,2 s

write oscillation for spring pendulum. replacement is 6cm = 0,06 m
if for measurement 1 write average T for forst measurement.
