What is momentum?
What is the principle of conservation of momentum?
What is impulse?
Calculate the average force on an object in a
collision, given the time of the collision and
the change in momentum of the object.
How can you use an understanding of impulse
to reduce the force on you in any kind of collision?
Given initial momenta of two objects, calculate
the velocity after they collide if the collision is
totally inelastic (i.e., they stick together).
What is meant by the center of mass,
and what is its significance?
How do you find the center of mass of
a collection of point masses?
How do you find the center of mass of
a continuous distribution of mass?
What constraint does the conservation
of momentum put on the particles involved
in a collision?
What is an elastic collision? What additional
constraint acts in an elastic collision?
Describe the velocities after a headon elastic
collision between equal masses where the
target mass is at rest before the collision.
Describe the same kind of collision if the
target mass is very massive compared to the
projectile. .. if the target mass is very small
compared to the projectile.
