the another name for vector product is cross product
The cross product a × b is defined as a vector c that is perpendicular to both a and b, with a direction given by the right-hand rule and a magnitude equal to the area of the parallelogram that the vectors span.
The cross product is defined by the formula
a X b = a *b*sin() n
where is the angle between a and b in the plane containing them (hence, it is between 0° and 180°), a and b are the magnitudes of vectors a and b, and n is a unit vector perpendicular to the plane containing a and b in the direction given by the right-hand rule

Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
Momentum = mass • velocity
In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as
p = m • v
where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.
------------------------------------------------------------
Inertia: the property of a body which resists to change the position of the body is called Inertia
mass is a measureof inertia
--------------------------------------------
Torque is defined as a twisting force that tends to cause rotation. We call the point where the object rotates the axis of rotation.
----------------------------------------------------------
a quantity expressing a body's tendency to resist angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation.
-------------------------------------------------------
the first requirement is net force acting on the system is zero
and second requirement is net torque acting on the system is zero
