Some properties of the vector product: If is parallel to(),then; If is perpendicular to,then The cross product of any two vectors and can be expressed in the following determinant form: Angular momentum of a particle The instantaneous angular momentum: The magnitude of is where is the angle...
Its magnitude is L= rp sin θ, where θ is the angle between r and p; its direction is specified by the right-hand rule for vector products (see Chapter 1). The units of angular momentum are kg·m2/s or slug·ft2/s. We will concentrate on simple rotational systems in which ...
The magnitude of the angular momentum may be expressed as (5.36)h=rVcosϕ The relationship between the variables is illustrated in Figure 5.10. When the normal component of velocity V sin ϕ is in the direction opposite to that of the radius vector the flight path angle ϕ is ...
