Chapter 9 Linear Momentum and Collisions
Linear Momentum
The linear momentum of an object of mass m moving with a velocity v is defined as
r r p = mv
the product of the mass and the velocity vector. S

The Vector Product
There are instances where the product of two vectors is another vector
Earlier we saw where the product of two vectors was a scalar
This was called the d

Force
Forces are what cause any change in the velocity of an object
A force is that which causes an acceleration
The net force is the vector sum of all the forces acting o

Motion in Two Dimensions
Using + or signs is not always sufficient to fully describe motion in more than one dimension
Vectors can be used to more fully describe mot
