=====Animated Derivation Videos of Chapter 7 - Oscillations=====

1. Simple Harmonic Motion
2. Circular Motion and SHM (Most Important)
3. Simple Pendulum
4. Energy Conservation in Case of SHM
5. Derivation of Displacement Formula x=xoCost

1. A force of 0.4 N is required to displace a body attached to a spring through 0.1 m from its mean position. Calculate the spring constant of spring.
2. A pendulum clock keeps perfect time at a location where acceleration due to gravity is exactly 9.8 ms-2 . When the clock is moved to a higher altitude, it loses 80.0s per day. Find the value of g at this new location.
3. Calculate the length of a second pendulum having time period 2s at a place where g = 9.8 ms-2.
4. A body of mass ‘m’ suspended from a spring with force constant k, vibrates with frequency ‘f1’. When it’s length is cut into half and the same body is suspended from one of the halves, the frequency is ‘f2’. Find out f1f2-1.
5. A mass at the end of spring describes S.H.M with T=0.40 s. Find out a ⃗ when the displacement is 0.04 m.
6. A block weighing 4.0 kg extends a spring by 0.16 m from it’s un-stretched position. The block is removed and a 0.50 kg body is hung from same spring. If the spring is now stretched and then released, what is its period of vibration.
7. What should be the length of simple pendulum whose time period is one second? What is its frequency?
8. A spring, whose spring constant is 80.0 Nm-1 vertically supports a mass of 1.0 kg is at rest position. Find the distance by which the mass must be pulled down, so that on being released, it may pass the mean position with velocity of one metre per second.
9. An 8000 g body vibrates S.H.M with amplitude 0.30 m. The restoring force is 60 N and the displacement is 0.30 m. Find out (i) T (ii) a ⃗ (iii) v ⃗ (iv) K.E (v) P.E when the displacement is 12 cm.
10. Find the amplitude, frequency and time period of an object oscillating at the end of a spring, if the equation for its position at any instant t is given by x=0.25 Cos (/8)t. Find the displacement of the object after 2.0 s.

[ZahidKhan-pscp]

Thank you so much for your efforts sir 😊😊

[simple._thing]

Soo nicely explained. Your videos really help alot in understanding the numericals especially with tons of mistakes in the kp book

[horiabatool]

sir, in numerical 2, if the watch is losing 0.000916 sec per sec at new location so why not we subtracted it from 1, intead we added 1sec in it?

[umamashoukat-kspe]

In the formula of acceleration i-e w2 so why the square over Omega is not taken in calculation ?in numerical 9

[is......]

Is there a logic why we are using the equation: T’ = 1.0009T ? How do we know this is true?

[iplayoverwatch]

Aoa sir will formulas be provided in board paper, ? They were provided in our matric paper last
year {federal board }

[rubaishakundi]

Sir numerical 2, 1 kaha se aya hai in find new location time period

[Aroob-xcof]

Why in the num 7 for finding frequency we are not using the formula f=2π√g/l

[usmanniazi]

Hum chapter k last numerical mein angle radian mein kiu ni lay rahay jab k example 7.3 aur assignment 7.4 mein radian mein Liyah hai

[RajaAbdullahKhan-mofv]

Sir your videos are very helpful for me God bless you🤲 conceptual questions ki bhi videos bnaya krain na 😊❤

[kingbobby-qunp]

sir plz make a video of math guess paper

[AhsanShabbir-vs]

sir num 2 ma sec cal krny ky bad 3.33/3600=926 ara h ap ak 916 smj ni aye ans ksy leh aye ap

[Lalanawasgyds]

Sir in numerical 10 how is coming Π/4 =45😢😮😮😮

[MuneebaYounas-zm]

Sir ap ny sec ki value ghalat put ki ha 3.33÷3600= 0.000925 ha pr ap ny 916 put ki ha plz explain

[moonlight_]

Thankyou sm for this.
When you'll start chapter 8?
