Physics - Test Your Knowledge: Moment of Inertia (13 of 24) Acceleration of a Wheel: Part 1/2

In this video I will find the:
a) angular acceleration, alpha=?, of a wheel with a constant force, F=10N, acting downwards;
b) work=kinetic energy, W=KE=?, at a distance, d=20m. Part1/2

To donate:

Very awesome video on mechanics
Sir I was good in maths and physics but one incident change my life(poverty), now I m totally away from physics and I m very sad
I promise myself to become a millionaire and help those who just wants to learn and the knowledge of Physics by the help of your , I mean people like you who r very smart in physics. Sorry I m English is weak if I make a mistake then forgive me .
Jai hind
Jai Bharat
And Sir You Are Great
Salute you sir I m from india

Kinetic energy (relative to point p) tends to confuse me, dependent upon an object's velocity (relative to a point p),
because it is an energy at an instantaneous point in time. Whereas work done takes place over a time period.

As delta theta is the differential of one revolution of the disk =2 pi, shoudnt 2 pi be included in the kinematic equation (or was it already included in d=R*theta)?

Can i ask question related to please reply ....and where i ask....in comment box..or any other??? M from india....
U r awesome the way u teach..
