FAQs on Ultimate JEE Main 2025-26 Laws of Motion Mock Test Preparation
1. What are Newton's laws of motion?
Newton's laws of motion are three fundamental principles that describe the relationship between the motion of an object and the forces acting on it. They are: First Law (Law of Inertia): An object remains at rest or in uniform motion unless acted upon by an external force. Second Law: The force on an object equals its mass times its acceleration (F = ma). Third Law: For every action, there is an equal and opposite reaction.
2. What is inertia as stated in the first law of motion?
Inertia is the property of a body to resist any change in its state of rest or uniform motion. Newton's first law of motion is also known as the law of inertia, which states that a body will continue in its state unless acted upon by an external force.
3. How can you mathematically express Newton's second law of motion?
Newton's second law of motion can be mathematically expressed as F = ma, where F is the net external force acting on the object, m is the mass of the object, and a is the acceleration produced. This law explains how the force applied to an object is directly proportional to the acceleration it experiences.
4. What is the law of conservation of momentum?
The law of conservation of momentum states that the total momentum of an isolated system remains constant if no external force acts on it. This principle is derived from Newton's third law and is fundamental in analyzing collisions.
5. Explain the difference between mass and weight.
Mass is the measure of the quantity of matter in a body and is a scalar quantity, while weight is the force with which an object is attracted towards the Earth and is a vector quantity. Weight is calculated as weight (W) = mass (m) × acceleration due to gravity (g).
6. What is friction, and how does it affect motion?
Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact. It slows down or prevents the motion of objects and can generate heat. Friction is necessary for activities like walking and driving but can also cause wear and tear.
7. What are balanced and unbalanced forces?
Balanced forces are equal in magnitude but opposite in direction, resulting in no change in motion. Unbalanced forces are not equal and cause a change in the object's state of motion, leading to acceleration or deceleration.
8. How do Newton's laws apply to rocket propulsion?
In rocket propulsion, Newton's third law is key: the rocket expels exhaust gases backward (action), and the rocket is pushed forward (reaction). Additionally, conservation of momentum explains how the change in mass and velocity of expelling gases propels the rocket upward.
9. What are some common applications of Newton's third law in daily life?
Some common applications include: Walking (feet push the ground backward, ground pushes forward), swimming (hands push water backward, water pushes body forward), and rowing a boat (oars push water backward, boat moves forward). All demonstrate equal and opposite reactions.
10. Why does a passenger lurch forward when a moving bus stops suddenly?
When a bus stops suddenly, the lower part of the passenger's body comes to rest with the bus due to direct contact, but the upper part tends to remain in motion due to inertia. This causes the passenger to lurch forward.
11. What factors affect the magnitude of friction between two surfaces?
The magnitude of friction depends on: 1) The nature of the surfaces in contact (smoother surfaces have less friction, rough surfaces have more), and 2) The normal force pressing the surfaces together. Friction can also be affected by lubrication and surface area contact.
12. What is meant by pseudo force? (New FAQ)
A pseudo force is an apparent force experienced by an object when observed from a non-inertial (accelerating) reference frame. It does not arise from any physical interaction but is introduced mathematically to explain the object's motion relative to the accelerating frame, such as when sitting in a suddenly accelerating or decelerating vehicle.
