Question

3. Define momentum and write its unit.​

Answer 1

Momentum, product of the mass of a particle and its velocity. ... Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.

The unit of momentum is the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity is in meters per second then the momentum is in kilogram meters per second (kg⋅m/s).

Explanation:

Momentum (Linear momentum) for moving body is defined as the product of mass and velocity.  If a body is moving with velocity, v and having mass, m then momentum of body is p =m×v.  SI unit of momentum (p) is kgms  raise to -1 .
