This man is a gift from God. Bless your beautiful soul for saving us all.

Loud and clear voice, excellent teaching!

WOW! I've been trying to understand this all day and your explanation was just...WOW! Thank you so much!!

Najma Ahmed congrats on grasping the concept! glad to see i was of help :)

Tysm. The energy of explanation made me listen with double of my attention, and I understood it so easily! Ty

Thank you so much for all the mini lectures you post. You really help me to understand different concepts from multiple different courses. You helped me be successful in online courses, and now that I am back on campus, you still help me understand concepts!

I love you. You are clear and thorough and simple concise. Thank you

superb sir. That really was a high quality lecture. Cleared all my doubts in one lecture.

I fall asleep during every lecture video on this, but ur voice kept me alert thank you.

Wow your explaning style was very good and clear any student can understand your lectures very well

Thank you so much i almost died trying to find the perfect explanation thank you so much for saving me phew I owe you

Your explanation skills are top tier.

Your explanation was mind blowing loving it

Very clear. Thank you so much! 😀

Wow 😲😲😳 man your explanation makes more sense than these other KZreadrs

You're amazing. Thank you.

This is the best site to learn physics topics.....Good

Manh....U rocked it again!

excellent teaching!

Crystal clear, thanks!

Excellent video.

wonderful lecture

please tell me that how amplitude effects simple pendulum

Thank you very much 💜

Extremely helpful, thanks!

Thanks Sir 👍

This.iz amazing

Thanku dear sir

I just want to add something else here: This formula for harmonic motion of the pendulum only works when it rotates in a small angle.

Thanks

Sir why the string is weightless And the bob is always spherical ?

@fahadtariq98

1) The string is not weightless, it has some weight but its weight is too less so we neglect its weight. 2) There are many reasons we take the object like a sphere. One of the reason is: the sphere object has the center of gravity in its center that's why the bob remains the same during its motion and it doesn't lose its balance. While the other objects with different shapes (like rectangle, triangle, etc.) will create many problems during motion so we take a spherical bob. Hope it helps!!

Resolving a given force in to its perpendicular components, giving sine and cos components (from their definitions). It comes from vectors.

You did not tell us why there is a negative sign between the force and the angular displacement

HOW FORCE IS IN OPPOSITE DIRECTION OF DISPLACEMENT ?NOT GETTING PLEASE HELP.

@ThePremez

The force always acts towards the equilibrium position (due to gravity) and the displacement is positive when it is moving away from the equilibrium position. That's all

Sir what is positive and negative displacement?

@seth5119

With repect to the X axis, as the mass swings towards position 1, we can say that its displacement is towards the negative X direction, and as it swings to position 3, we can say that its displacement is towards the positive X direction. Since we are taking position 2 to be our zero point, or point of equilibrium.

lets do the cycloid minus the circular.

You said so much, however you guys never confirm what the Kinetic energy force actually is at half of the descent to the KE, by starting at 100 J which is be beginning PE value, which is at 100 Joules KE (all the way at the bottom of the pendulum swing), and the back to 0 Joules KE all the way at the top. Then you also never confirm the same for the other side; half way to the bottom/half way to the top. How many jewels is that? PE = KE. All you guys mention at that point is that Your formula and cancellations to make the equivalent look great. If you begin with 100 J for the PE, then at half the pendulum swing when the pendulum is all the way at the bottom and KE is 100 J, what is the PE and the KE, when the pendulum is half way between the top point of release and the bottom/end of the kinetic energy drop. Same on the other side; which appears to me to be at energy level 50J, half. Please confirm me because I see no actual data calculations any place. Just formulas. Thank you.

to us educated from KZread

Why would you use F=-kx as a restoring force for the simple pendulum. The equation applies to elastic materials (Hooke's law) where the force is proportional to the elongation. Maybe you could use the general definition of simple harmonic motion (a = -w^2x) to derive the frequency. -mgx/L = -ma = -mw^2x ---- Simplifying, w=sqr (g/L)
