JEE Advanced Important Questions of Newton's Laws of Motion and Friction
FAQs on JEE Advanced Newton's Laws of Motion and Friction Important Questions
1. What are the laws of friction that may be asked in the JEE advanced exam?
There are five laws of friction. The first law states that when an object moves, friction is proportional and perpendicular to its force. The second law states that friction experienced by an object is dependent on the nature of the object. The third law of friction states that friction does not have anything to do with the area of contact. The fourth law of friction states that kinetic friction is not affected by velocity. The final law of friction states that the coefficient of kinetic friction is lesser than the coefficient of static friction.
2. According to the chapter Newton’s Motion and Friction for JEE Advanced, who discovered the three laws of motion in physics?
Sir Isaac Newton discovered the three laws of motion in physics. He was an English astronomer, physicist, theologian, mathematician. He was a key figure in the philosophical revolution of enlightenment. Likewise, he also made considerable contributions to optics. He was a fellow of Trinity College and also taught at the University of Columbia. Most of his works were unpublished till his death.
3. How is Newton’s law of motion different from Kepler’s law of motion as discussed in chapter Newton’s Laws of Motion and Friction for JEE Advanced?
Newton’s law describes motion in every object that we generally encounter. He gave three laws to explain the reason behind its motion, then explained related concepts through it. Unlike him, Kepler’s laws of motion mainly explain motion in planetary objects like stars, planets and asteroids. It tells us how they orbit and other related concepts. It also explains the velocity of different planetary bodies at different times.
4. According to the chapter, Newton’s Laws of Motion and Friction for JEE Advanced, what are the examples of Newton’s laws of motion?
Sir Isaac Newton contributed three laws of motion to physics. The first law is also known as inertia. A ball falling on the ground from the atmosphere is an example of this law. An example of the second law of motion is a guy pedalling a cycle and riding it. The force he puts on the pedals determines how fast the cycle moves. Finally, a rocket propelling up with the help of the fuel is an example of Newton's third law of motion.
5. According to the chapter, Newton’s Laws of Motion and Friction for JEE Advanced, what is Newton’s third law of motion all about?
Sir Isaac Newton has contributed 3 laws of motion to Physics. The third law of motion states that every action by an object has an equal and opposite reaction. His thought process started when he saw an apple falling and questioned the reason why it fell instead of going up. The best example for his third law of motion is when a ball hits the ground, it will bounce back with the same energy, stating that every action has an equal and opposite reaction. These answers are available at the Vedantu website for free.
6. What is Newton's law of motion IIT?
Newton's law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This is often stated as: “Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.”
7. What are the topics in Newton's laws of motion?
Newton's laws of motion encompass three main topics:
Newton's First Law: The law of inertia.
Newton's Second Law: F = ma (Force equals mass times acceleration).
Newton's Third Law: For every action, there is an equal and opposite reaction.
8. What are the 2 marks laws of motion?
In JEE Advanced, when referring to the "2 marks laws of motion," it typically means the fundamental laws of motion that are often asked about in the examination. These laws are:
Newton's First Law:
This law states that an object remains at rest or in uniform motion unless acted upon by an external force. Inertia is a consequence of this law.
Newton's Second Law:
This law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration. Mathematically, F = ma
where F is the force applied, m is the mass of the object, and a is its acceleration.
9. What law is inertia?
Inertia is described by Newton's First Law of Motion. It states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
10. What is inertia of a body?
The inertia of a body is its tendency to resist changes in its state of motion. In simpler terms, it's the resistance an object has to any change in its motion.
11. What is the golden age of physics?
The golden age of physics typically refers to the period between the late 19th and early 20th centuries, particularly from the late 1800s to the 1930s. This era saw groundbreaking discoveries and developments in various fields of physics, including relativity, quantum mechanics, electromagnetism, and nuclear physics. Some key figures of this era include Albert Einstein, Max Planck, Niels Bohr, and Marie Curie.
