## FAQs on Linear Momentum Video Lecture - Physics for JEE Main & Advanced

 1. What is linear momentum?
Ans. Linear momentum is a fundamental concept in physics that describes the motion of an object. It is defined as the product of an object's mass and its velocity. Mathematically, linear momentum (p) can be calculated as p = m * v, where m is the mass of the object and v is its velocity.
 2. How is linear momentum different from velocity?
Ans. Linear momentum and velocity are related concepts but are not the same. Velocity refers to the rate at which an object changes its position, while linear momentum refers to the quantity of motion an object possesses. While velocity is a vector quantity, having both magnitude and direction, linear momentum is also a vector quantity, but its direction is determined by the velocity vector.
 3. What is the principle of conservation of linear momentum?
Ans. The principle of conservation of linear momentum states that the total linear momentum of a system remains constant if no external forces act on it. In other words, the total momentum before an event or interaction is equal to the total momentum after the event or interaction, as long as no external forces are involved. This principle is based on Newton's third law of motion.
 4. How is linear momentum related to Newton's second law of motion?
Ans. Newton's second law of motion states that the force acting on an object is equal to the rate of change of its linear momentum. Mathematically, it can be expressed as F = dp/dt, where F is the net force, dp/dt represents the rate of change of momentum, and t is the time. This equation shows the direct relationship between force, momentum, and acceleration.
 5. Can linear momentum be transferred between objects in a collision?
Ans. Yes, linear momentum can be transferred between objects during a collision. According to the law of conservation of linear momentum, the total momentum of a system before a collision is equal to the total momentum after the collision. In a collision, the momentum of one object may decrease while the momentum of the other object increases, depending on the masses and velocities involved. However, the total momentum of the system remains constant.
