Physics

This chapter covers topics like physical units, measurement of length, measurement of time, measurement of mass, measurement of volume, and experimentation.

In this chapter, we will learn about motion in one dimension. It describes the concept of speed, velocity, acceleration, and uniform and non-uniform motion. We will also explore the graphical representation and equations of motion with derivatives.

This chapter covers topics like force, newton's laws of motion, and momentum.

In this chapter, we will learn about the gravitational force and its units in detail. It discusses the concept of free fall, along with the equation of motion of objects. It also describes the differences between mass and weight.

This chapter explains the terms thrust, pressure, and density, along with their units. We will learn the various laws of liquid, hydrostatic paradox, and atmospheric pressure. It also briefs on buoyancy, Archimedes' principle, and laws of floatation.

In this chapter, we will study the concept of heat and temperature. It illustrates the thermal equilibrium and thermal expansion, along with their differences. We will also learn about the anomalous behaviour of water with the help of experiments.

In this chapter, we will learn about the food chain, food web, energy flow, and laws of thermodynamics. It describes various sources of energy in brief. It also discusses the environmental consequences, energy degradation, and the greenhouse effect.

Through this chapter, we will learn about the concept of light. We will discuss the artificial and natural sources of light, along with the properties of light. We will also understand the notion of shadows.

This chapter comprises the details of loudness, pitch and quality of sound. It describes the musical instruments which include wind instruments, stringed instruments and the percussion instruments. We will also learn about the unit of loudness.

This chapter sheds light on the current electricity. It discusses the sources of direct current, electric circuits, and detection of current through diagrams. It also describes Ohm’s law, electrical resistance, and conductors and insulators.

This chapter explains the differences between magnetic and non-magnetic substances along with their characteristics and properties. It discusses the magnetic field around a magnet, and permanent and temporary magnets along with their uses.
