Difference between Mass and momentum
Mass
1.) Mass of object is the quantity of matter present in its state of rest.
2.) Mass provides the inertial forces to the object when it is in rest. i.e. inertia at rest possessed by body is due to its mass only.
3.) It is independent of any other quantity for its measurement.
4.) Mass of object remains constant throughout the universe.
5.) Mass is scalar quantity.
6.) SI unit of mass is kilogram and that of CGS unit is gram.
Momentum
1.) Momentum is the quantity gained by body due to its motion.
2.) Momentum provides the inertial forces to object when it’s in motion. i.e. inertia at motion possessed by body is due to its motion only.
3.) Momentum depends on mass and velocity of object and defined as the product of mass and velocity of object. Given by,
momentum , P = mass ×velocity.
4.) Momentum of object can change with change in velocity of object.
5.) Momentum is vector quantity.
6.) SI unit of momentum is kilogram- meter/second (kg-m/s).
