Lakhmir Singh Solutions Class 9 Physics

Chapter 1: Motion
Chapter 2: Force and Laws of Motion
Chapter 3: Gravitation
Chapter 4: Work and Energy
Chapter 5: Sound

Chapter 1: Motion

Motion is defined as the movement of an object. There are different terms that are used to explain the motion of an object, and they are distance travelled, speed, acceleration, and laws of motion. There are three laws of motion, and these laws are explained with the help of diagrams and graphs. Also, the derivation of these laws is explained in the chapter.

Following is the table explaining the number of questions that are present in Chapter 1:

Very short answer type questions 36
Short answer type questions 29
Long answer type questions 16
Multiple-choice questions 25
Higher-order thinking skills questions 19
Total questions 125

Chapter 2: Force and Laws of Motion

Force is defined as either a push or a pull that is experienced by the body. Force is responsible for the change in velocity, direction, and shape of the body. Momentum, conservation of momentum, and laws of motion are the other concepts that are explained in Chapter 2. All the concepts are supported with relevant numericals, along with solved examples for better understanding.

Following is the table explaining the number of questions that are present in Chapter 2:

Very short answer type questions 33
Short answer type questions 37
Long answer type questions 10
Multiple-choice questions 20
Higher-order thinking skills questions 5
Total questions 105

Chapter 3: Gravitation

Why does the ball return back to the ground when it is thrown upwards, but the rocket flies to outer space? The answer is gravitation. Every object in the universe attracts every other object, and a certain amount of speed is required to make an object go to outer space. These are the concepts that are covered in Chapter 3. Also, learn how Newton’s third law of motion is related to gravitational force.

Following is the table explaining the number of questions that are present in Chapter 3:

Very short answer type questions 52
Short answer type questions 51
Long answer type questions 13
Multiple-choice questions 25
Higher-order thinking skills questions 18
Total questions 159

Chapter 4: Work and Energy

Work is said to be done when a force is applied to make an object move. To do this, energy is required. Also, work can be either positive, negative, or zero. There are different forms of energy, such as kinetic energy, potential energy, heat energy, light energy, chemical energy, sound energy, nuclear energy, and electrical energy. Apart from this, learn about the working principle of the simple pendulum in this chapter.

Following is the table explaining the number of questions that are present in Chapter 4:

Very short answer type questions 39
Short answer type questions 42
Long answer type questions 12
Multiple-choice questions 22
Higher-order thinking skills questions 15
Total questions 130

Chapter 5: Sound

Sound is a form of energy and is produced with the help of vibrations from objects. Sound always travels in the form of waves, and they are of two types: longitudinal waves and transverse waves. Wavelength, amplitude, and frequency are some of the characteristics of sound waves. Learn more about sound in Chapter 5.

Following is the table explaining the number of questions that are present in Chapter 5:

Very short answer type questions 77
Short answer type questions 43
Long answer type questions 15
Multiple-choice questions 28
Higher-order thinking skills questions 11
Total questions 174
