Question

Momentum?

Answer 1

Momentum can be defined as “"mass in motion” . All objects have mass, so if an object is moving then it has momentum . Momentum depends upon mass and velocity. In Newtonian mechanics, there is linear momentum and translational momentum and it is the product of mass * velocity .

It's dimensionally equivalent to impulse, the product of force * time . Newton's second law of motion states that change in linear momentum of a body is equal to net impulse acting on it .

Linear momentum is a vector quantity

It is also a conserved quantity , if a closed system is not affected by external forces , its total linear momentum cannot change .
