AP Physics: Mechanics
Momentum, Impulse, and Collisions: Chapter 8
Students will learn that:
o The momentum of a particle is a vector quantity equal to the product of the particle’s
mass and velocity.
o The impulse of the net force on a particle is the product of the net force and the time
interval. This quantity is also the change in momentum
o The total momentum of a system of particles is the vector sum of the momenta of the
individual particles
o An internal force is a force exerted by on part of a system on another. An external force
is a force exerted on any part of a system by something outside the system.
o In collisions of all kind, the initial and final total momenta are equal. In elastic collision
between two bodies, the initial and final total kinetic energies are also equal and the
initial and final relative velocities have the same magnitude. In an inelastic collision the
total kinetic energy is less after the collision than before.
o The position vector of the center of mass of a system of particles is a weighted average
of the positions of the individual particles
o The total momentum of a system equals its total mass multiplied by the velocity of its
center of mass. The center of mass moves as though all the mass was concentrated at
that point.
o In rocket propulsion, the mass of a rocket changes as the fuel is used up and ejected
from the rocket. Analysis of the motion of the rocket must include the momentum
carried away by the spent fuel as well as the momentum of the rocket itself
