Physics

This chapter enhances our knowledge of various types of forces. It discusses laws related to the motion of an object. Furthermore, it includes some graphs for uniform and non-uniform motion. It also briefs on the balanced and unbalanced forces.

In this chapter, we will learn in detail the concept of energy and the relationship between work and energy. We will further study potential and kinetic energy which is present in the body during rest or in motion.

This chapter talks about the potential and potential difference of a cell, free electrons, and the current flowing through a wire. It also briefs on the conductors and insulators. Moreover, it discusses Ohm’s law and resistance.

This chapter discusses different components of the computer and the types of software. It explains the importance of IT in science and technology, uses of information communication, and different opportunities in the computer field.

This chapter explains the laws of reflection. Light is the medium of illumination that makes sight possible. It discusses the types of reflection with the help of a diagram. It discusses the function and uses of a kaleidoscope and a periscope.

This chapter describes the effect of temperature, density, and molecular weight on the speed of light. It also explains the concept of reflection of light. Furthermore, it explores the structure of the human ear and gives an idea about sonography.

This chapter explains the different types of light. It describes optical and radio telescopes. Moreover, it tells us about the Indian Space Research Organization (ISRO) situated in Bengaluru. We will also discuss Science and Technology in brief.
