Rolling motion
Rolling motion is that motion in which rotattion occurs about a point or rotation about center of mass of that object.... discussion about conservative and non-conservative force and static friction
Ishant Goel
Solid sphere
Introduction about solid sphere, and questions and figure of solid sphere, rod and density of rod and moment of inertia of a hollow sphere about diameter
Some general features
These are some general features of gravitation like angular momentum and energy, motion of particle and plane polar co-ordinates And some related problems and examples
Gravitation
Gravitation is one of the important topics of physics especially dynamics and term like gravitational potential is equally important.... Gravitational field for simple pendulum and spherical shell
CM of various objects
These are the notes of center of mass of various objects like Semi-circular ring, semi-circular disc, hemispherical shell, solid hemisphere, solid cone and some examples too
Fundamental of dynamics
This lecture includes Newton's laws, definition of inertial frame and non-inertial frames, gallilean and acceleration transformation and at last, there are fundamental laws
System of particles
This lecture includes the most important topic of dynamics i.e centre of mass and change in linear Momentum.... Questions for finding the centre of mass
Variable mass system
In variable mass system, firstly we will discuss rocket motion in which we find rate of increase of fuel mass... and there are two cases in that, first one is "no gravity" and second is "in gravity"
Angular momentum
Angular momentum of a system of particles , Rotation about a fixed axis and it's geometrical concept and related questions for practice
Moment of Inertia
Moment of inertia is also an important aspect for rotational dynamics... Here moment of inertia for a uniform ring is discussed... Perpendicular axis theorem for a plane lamine and 3-D object
Method of undetermined coefficients
The method of undetermined coefficients is also a very significant method to solve differential equations... Basically in this method, we assume two or three coefficients in the differential equations and then find it's value and finally we got the answer
Second order equations
These are the second order partial differential equations with both types of constants...some as fixed coefficients and some has variance constant and both types of questions are discussed
