9 Center of Mass and Momentum
9.1 The Center of Mass
9.1.1 Symmetry and the Center of Mass
A uniform metal plate P of radius 2R from which
a disk of radius R has been stamped out.
9.2 Newton’s Second Law for a System of Particles
9.3 Linear Momentum
9.4 The Linear Momentum of a System of Particles
9.5 Collision and Impulse
9.5.1 Single Collision
9.5.2 Series of Collision
9.6 Conservation of Linear Momentum
If no net external force acts on a system of particles,
the total linear momentum of the system cannot change.
9.7 Momentum and Kinetic Energy in Collisions
If the total kinetic energy of a system remains unchanged
by the collision, then the kinetic energy of the system is conserved. Such a collision is called an elastic collision.
9.8 Inelastic Collisions in One Dimension
9.8.1 Completely inelastic Collision
9.8.2 Velocity of the Center of Mass
9.9 Elastic Collisions in One Dimension
9.9.1 Stationary Target:
9.9.2 Moving Target:
9.10 Center of Mass Frame
If we view the collision in the center of mass frame,
the velocities of two colliding bodies may change their directions but not their magnitudes after the collision.
