Can anyone please tell me the important topics of the chapters Newton's laws of motion, work energy and power, system of particles and rotational motion and last chapter gravitation.
please i need only the important topics and derivations.
It's urgent, please do answer only if you know.

Chapter 5 – Laws of Motion
Important Topics:
1. Newton’s First Law of Motion
2. Newton’s Second law of Motion
3. Newton’s Third Law of Motion
4. Conservation of Momentum
5. Circular Motion
6. Problem Solving in Mechanics
Tips:
a) It is the most important chapter in mechanics. All the three laws of Newton should be well understood and you should be able to relate these laws to general day to day life activities.
b) Numerical is frequently asked based on the conservation of momentum. These problems do include the conceptual steps taken from three laws of Newton’s while solving the problem.
c) Quality questions are asked from mechanics involving friction and resolving forces into various components and equalizing them.
d) A brief knowledge and practice of a variety of problems from these topics is the only way to solve such problems.
Chapter 6 – Work, Energy, and Power
Important Topics:
1. Work-Energy Theorem (variable force)
2. Kinetic Energy and Potential Energy
3. Law of Conservation of Energy
4. Potential Energy of a Spring
5. Collisions
Tips:
a) The derivation of all the mentioned topics is important.
b) Theoretical questions are hardly asked from the topic. However, a wide range of numerical problems is being asked.
c) Numerical involving conversion of energy and conservation are asked. These numerical include the concept of kinetic and potential energy.
d) Work done is asked several times in various conversions.
e) Collison is a very important topic for both theoretical short questions and numerical.
f) The potential energy of spring’s derivation and expression is an important topic. Interpretation of potential energy curve is very important.
ask me derivation in details !!
in fb but sneha whose id what is your id !!
I'm block sneha id
one is send me your physics paper plzz. ok
Chapter 7 – Systems of Particles and Rotational Motion
Important Topics:
1. Centre of Mass and its Motion
2. Linear motion of System of Particles
3. Angular Velocity and Angular Acceleration
4. Torque and Angular Momentum
5. Moment of Inertia
6. Theorems of perpendicular and Parallel Axis
7. Kinematics of rotational motion about a fixed axis
8. Dynamics of rotational motion about a fixed axis
9. Angular momentum in case of rotation about a fixed axis Rolling motion
10. Rolling Motion
Tips:
a) All the mentioned important topics are equally asked in form of numerical problems as well as derivations. Conceptual understanding of each topic is recommended. Also, practice numerical from each.
b) Do not get confused between rolling motion with and without slipping.
c) Revise the relations between the physical quantities in the chapter.
d) Make a chart or table for the moment of inertia for different objects and shapes.
Chapter 8 – Gravitation
Important Topics:
1. Kepler’s Law
2. Universal Law of Gravitation
3. Acceleration due to gravity
4. Gravitational Potential Energy
Tips:
a) Kepler’s law can be asked directly.
b) Both numerical and direct questions or derivations can be asked from the universal law of gravitation, the acceleration due to gravity.
c) Derivation of the value of G and g is also important. Derivation of acceleration due to gravity both below and above the Earth surface is important. Often numericals based on the relation between this variation in the value of g is also asked.
d) Memorize the relations on a tip.
e) Escape speed and time period of satellites are important topics for numerical. deriving the escape speed for certain planet or body can also be asked.
f) The concept of weightlessness is good for awareness and understanding the concept more clearly. Both the types of satellites, geostationary and polar do not require intensive learning.
byeee best of luck !!!
