Force and laws of motion is an important chapter in the class 9 NCERT syllabus that covers the most basic concepts in physics: the laws of motion and the concept of force and momentum. The solutions are provided to ensure that students can save time while studying. Students can refer to the laws of motion class 9 NCERT solutions provided by MSVGo as an overview of the content in the textbook and even use it for a quick revision before the exams. Make sure also to check out various visualisations, study material, and other resources to get a strong grasp of the subject.
Topics covered in Chapter 9 – Force and Laws of Motion (Content Table)
Newton's First Law of Motion
Newton's Second and Third Law of Motion
Law of Conservation of Momentum
When an object changes its position with reference to its surroundings, it is said to be in motion. Changes in the object's position can be measured by taking another moving or stationary body as a reference. For example, if a person is cycling from one place to another, the cyclist is said to be in motion with respect to the road. A movement can be in a straight line, a circular path, or a combination of different lines of paths. If an object moves in a straight line, it is said to be moving in a straight-line motion. For example, a train moving along a track.
Force can be defined as an external influence that changes the state of rest or uniform motion in a straight line. Force can bring about motion in a body, stop it or even change its direction. It can produce, modify or destroy energy.
Force can be applied in a push or pull direction upon an object, depending on its interaction with another body. Whenever two objects interact, a force acts upon each of the objects.
Force is a vector quantity that has both magnitude and direction. When two forces act on a body in opposite directions, they tend to cancel each other, resulting in zero. This is known as balanced force. But, when the two forces act along the same line of action, they combine to form a single force whose effect is equal to their sum. This is called an unbalanced force.
