Chapter no.1 Vector Operation:

1. SCALARS

The physical quantities which are completely described by magnitude with the proper unit are called scalars. Mass, length, time density, energy, work, temperature, and charge are examples of scalars. Scalars can be added, multiplied, and subtracted by ordinary rules of algebra.

2. VECTORS

The physical quantities which are completely described by magnitude, with proper unit and

direction are called vectors. Force velocity, acceleration, momentum, torque, electric field intensity, and magnetic field induction are examples of vectors. Vectors are added, multiplied, and subtracted by vector algebra. However, parallel and antiparallel vectors are added by ordinary algebra.

Chapter # 2: Particle Dynamics

In this chapter, we continue with the applications of Newton’s laws. We study frictional forces and their consequences. We discuss non-constant forces and show how to solve the equations of motion for such forces.

Finally, we show how using a non-inertial reference frame produces effects that can be analyzed by introducing inertial forces or pseudo-forces that are not caused by specific objects in the environment.
