[00:00:00]Chapter harmonic F= KX X= A maxibrium.

[00:01:14]Similar kind of.

[00:01:30]Okay.

[00:01:39]Same case.

[00:01:44]Similarly, function of time.

[00:02:19]AIS equilibrium X= 0 x= t23 t45 and so on and so on Second tal to three. Second point, Tin Omega T.

[00:04:02]Max.

[00:04:21]Similar.

[00:04:26]Same direct max phase.

[00:04:58]Delta. Sorry.

[00:05:17]differential master square equation velocity dx² by dt² dx² by dt² + omega square XL a sme 4 x + 2 x + 3 Equation solution.

[00:06:59]kx = a sin omega tiant Omega d by dtim dx² by dt² a Sin square.

[00:07:58]Sorry.

[00:08:06]Very excess depending on pretty Easy cos square something + sin square something 1 - sin square something 1us square t x whole square.

[00:09:08]Sorry x² a square x² Omega square.

[00:10:02]Right side pretty easy.

[00:10:24]x = a sin omega t + delta v = roo<unk> a² - x² amega square x maximum value Maximum one maximum.

[00:11:09]Maximum value.

[00:11:31]Max a square root a square.

[00:11:55]By the way, Vinum Valibrium position max.

[00:12:49]Similarly, similar respect minis important Omega square max.

[00:13:47]Similar goes for this point.

[00:13:58]Big maximum.

[00:14:10]Same goes for spring.

[00:14:25]foreign equal 0.

[00:14:50]Sine wave distance.

[00:15:11]Period.

[00:15:19]Very easy. 2 pi roo<unk> l 2 pi roo<unk> m by k Easy kome square.

[00:15:44]Sorry. Omega square root.

[00:16:02]by root kinter constant.

[00:16:29]very important.

[00:16:42]Pretty important.

[00:16:50]Part one. Part two.

[00:16:57]comprehensive very important.

[00:17:09]See you guys in the next part. Part two of not sure.

[00:17:16]Let's see.

[00:17:18]Simple harmonic motion.

[00:17:30]Kinetic energy potential energy easier dx square need Fore Maxial energy half k a square Maxial Max EP max half a square connect a square ideal half k²us jus x² Half M V² A square - X² K M K by M K roo<unk> sorry K A square E original energy Maxinet max.

[00:20:51]important half a square k x² x² Cabotial energy half x² X² K X potial energy potential energy max square.

[00:22:40]Sorry.

[00:22:53]formula t 2 pi roo<unk> l by gro 3.14 9.85 by 86 approximately 9.8 Approximately 2 seconds.

[00:23:30]Theoretically full second In a sense number of oscillation Second.

[00:24:14]Second.

[00:24:16]Slowly.

[00:24:18]Slowly.

[00:24:29]0.5 second.5 Second one second.

[00:24:55]for second.

[00:25:19]864 864 0 divided by 864 0.

[00:25:33]2 / 10 / 10 + - 2 8 10 / 12.

[00:26:04]Up to you.

[00:26:10]L if I'm not wrong.

[00:26:37]Very important.

[00:26:50]Very important.

[00:26:58]Forefather clock disop square.

[00:27:37]Same goes for root.

[00:27:45]square rectangular hyperola deep G 9.8 Ga Rid square one by roo<unk> over G 1 by roo<unk> over GH root over 1 by Gal G / H R + H / R² + H² H R square T 9.8 1 + h / r easy root over g root over G Hul G 1us R 1 by 1 - D / R 1 + t 1 by 1 - t by r pretty easy force kx X 2 important spring.

[00:31:32]Same time only spring constant kind of spring attach Strongly sorry Spring= kx2 spring constant Force restoration force force kind of important.

[00:33:33]for sorry 1 by K 1 by K1 + 1 by K2 K2 Spring 1x k 1x k1 plus 1x k2 k1 k2 pretty easy.

[00:34:51]More S M + N / N.
