Momentum of a body is 1. a vector quantity. 2. a conserved quantity in an isolated system. 3. same as force in linear motion. Select the correct answer using the code given below :

Momentum is defined as the product of an object's mass and its velocity (p = mv). Since velocity is a vector quantity, momentum is also a vector quantity, possessing both magnitude and direction [t2, t5, t6]. According to the Law of Conservation of Momentum, the total momentum of an isolated system remains constant provided no external net force acts upon it [t2, t3, t7]. However, momentum is not the same as force. In linear motion, force is defined as the rate of change of momentum over time (F = dp/dt), as established by Newton's Second Law [t1, t4, t8]. While force influences momentum, they are distinct physical quantities with different SI units (Newtons for force and kg·m/s for momentum) [c3, t4, t5]. Therefore, statements 1 and 2 are correct, while statement 3 is incorrect.
