FAQs on NCERT Solutions for Class 9 Science Hindi Chapter 9 Force and Laws of Motion
1. Explain the laws of motion covered in Chapter 9 of NCERT Solutions for Class 9 Science.
The motion of bodies is described by Newton's three laws of motion. The laws of motion are known as Newton's Laws. The first law tells about the law of inertia. The second law talks about momentum. The third law proves that there is a reaction to every action. All the laws define the link between the forces applied to a body and the motion it experiences as a result of those forces.
2. Which concepts in the NCERT Solutions for Class 9 Science Chapter 9 are important from the exam perspective?
Balanced and Unbalanced Forces, First Law of Motion, Inertia and Mass, Second Law of Motion, Third Law of Motion, Conservation of Momentum are some of the themes addressed in the Chapter Force and Laws of Motion, which are also important from the exam perspective. However, Vedantu offers a comprehensive and well-organized concept-based learning solution designed to instil confidence in students as they prepare for the CBSE and competitive exams. For simplicity of use, NCERT Solutions of Chapter 9 for Class 9 Science are accessible in both PDF and online versions free of cost on the Vedantu website and mobile app.
3. Define force.
Aristotle defined a force as anything that causes an item to move in an “unnatural” way. One of the earliest scientists to investigate gravity and force was Sir Isaac Newton. Any force is just a push or a pull. A push or pull on an item can be expressed as it is. Force may cause a still body to move, or it can halt or slow down a moving body.
4. What is balanced force?
We call two forces operating on an item balanced when they are equal in magnitude yet operate in different directions. This is what occurs when the forces operating on an item are balanced (or there are no forces acting on it). A moving item continues to travel at the same pace and in the same direction as a stationary object. For more information on this topic, visit Vedantu.
5. Why is it advised to tie any luggage kept on the roof of a bus with a rope?
When some baggage is placed on the top of a bus that is originally at rest, the vehicle's forward acceleration will impose a force on the luggage (in the backward direction). Similarly, when a bus comes to a complete stop owing to the use of brakes, a force (in the forward direction) is imposed on the luggage.
