Prove that if a body is thrown vertically upward the Time of Ascent is e...

In this lecture we try to understand why when a body is thrown
vertically upward the time of ascent is equal to the time of descent.
This will further help us to understanding the motion of projectiles.

Final speed of object dropped from height h using Motion Equations & Ene...

In this lecture we derive final speed of an object which falls from a
height h with no initial speed to the ground (no air resistance) using
Equations of motion and Conservation of Energy principle.

Derivation of 3 equations of motion | v = u + at | v² = u² + 2as | s =...

In this video we derive the three equations of motion. And we have a
detailed discussion on acceleration (zero acceleration, positive
acceleration & negative acceleration.) Velocity Time graphs are
discussed in detail. No calculus is being used and we use basic algebra
only. Video also has worksheet with answers in the end. The video will
help 9th, 10th, 11th, 12th students from all boards. The three equations
of motion help in projectile motion and are also helpful in rotational
motion.

Derivation of Centripetal Force & Acceleration | Uniform Circular Motion...

In this video we do derivation of Centripetal Force and Acceleration
using Vector for Uniform Circular Motion using vectors.
|F=m(v^2)/R=m(ω^2)R| We start with revision of angular / linear
velocities. Working knowledge of Calculus would help you to understand. 

Also have a look at the previous videos in the below playlist:

Electricity Numericals {R = ρ*L/A || Heating Effect of Electric Current}

This video has discussion on Resistivity; followed by numericals based on Resistivity and Heating effect of current. Questions from IGCSE past papers have been solved.Discussion on common pain points that students face while solving Electricity problems is discussed and also how to avoid common pitfalls.
