This post is to guide the students who have opted for Physics as a subject for their class 11. We will have a broad view of the topics and chapters to be studied and also refer to the books and online study materials as a quick reckoner…

**Here you will get 2 sets of IGCSE physics force and motion worksheet with numerical problems with solution.** You will get ample scope to test your understanding of motion equations and force concepts.

The solutions of worksheet set 1 are given on this page itself. And the solution of set…

Gustav Kirchhoff, an eminent German physicist is the person behind Kirchhoff’s first law dealing with electric current. This law is also known as Kirchhoff’s Current Law or KCL. **…**

Derivation of the Equations of Motion: To calculate quantities involving motion in a straight line at a constant acceleration we need four equations. These equations are often informally referred to as the ‘suvat equations’ after the symbols used for the 5 quantities involved.

We will derive equations for the following…

The **Refractive index** of a medium is an important topic of optics or the Light chapter of physics. Solving the numerical problems from this chapter is also a must if we want a good grasp on chapters like the Refraction of light.

We use a *number of formulas* to solve…

For high school students with science, the chapter on ‘Gravitation and gravitational force’ is quite interesting because it talks of that force that is working between any 2 objects in existence. As we find ourselves standing on the land of this planet it’s because of this force.

Here are a few links where you will find interesting coverage in this chapter.

Numerical problems on gravitational force

Here we will work on the **derivation of the Terminal Velocity equation or formula **using Stokes’ Law.

**Derivation of Terminal Velocity Equation**

When an object is falling through a fluid, in that case, if we want to analyze its motion (and find out its acceleration, if any) then we need…

Fear of uncertainty and nervousness about the future are two dangerous enemies our mind face every now and then. Fear about exams chase us from our childhood.

When we grow up enough to take up a job then comes fear and uncertainty to land up with a decent job, and…
