30kg/ms is the momentum of an 10 kg bowling ball rolling at 3 m/s.
What is momentum?
As momentum depends on both velocity and the direction of the body's motion, it is quantified by "mass velocity". Since velocity is a vector and mass is a scalar, momentum is a vector quantity. Mass times speed equals momentum.
p = mv
where m is the mass of the object , v is the velocity of the object.
From this, we get
p = 10 kg × 3 m/s
= 30 kg m/s
What is velocity?
The direction of a body or object's movement is defined by its velocity. In its basic form, speed is a scalar quantity. In essence, velocity is a vector quantity. It is the speed at which distance changes. It is the displacement change rate.
