Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on t
to grant the properties of hydrogen bridges. The thing is: the minimum to count as explanation is to goone level deeper. If the narrative merely restates the observation in different words then the narrative
Study the law of conservation of angular momentum. Understand the conservation of angular momentum formula, and explore real life conservation...
The law of conservation of angular momentum can be observed in other ways as well. For example, figure skaters, high divers and even people sitting in rotating chairs candemonstratethis law. If they spin with their arms stretched out, they'll continue to spin until an outside force is appli...
© M.Dubson, University of Colorado at Boulder Conservation of Angular Momentum = "Spin"We can assign a direction to the angular velocity:direction of ω = direction of axis + right hand rule (with right hand, curl fingers in direction of rotation, thumb points in direction of ω.) ...
Example 1. Calculating Angular Momentum of the Earth Strategy No information is given in the statement of the problem; so we must look up pertinent data before we can calculate L = Iω. First, according to Figure 1, the formula for the moment of inertia of a sphere is Figure 1. Some ...

(mass and radius) and angular velocity. If shape of object changes, inertia will change (see wkbk p.43). For example I=mr 2 for a wheel but I=1/2mr 2 for solid cylinder. So, if you are calculating the angular momentum of a wheel L=Iω changes from L=(mr)ω to L=(mr 2 ...
