Theory
The momentum of an object is its mass multiplied by its velocity. Momentum is a vector,
so the direction is important.
QUESTION 1: In this experiment the motion is one-dimensional. How can you account for the
direction of momentum in this case?
The kinetic energy of an object is given by KE = 12 mv . Kinetic energy is not a vector,
so you don't need to worry about direction.
QUESTION 2: In this experiment you will be determining whether momentum and kinetic
energy are conserved. What does it mean for a quantity to be conserved in a collision?
There are several types of collisions to investigate in this experiment. These are:
. Super-elastic, in which kinetic energy is larger after a collision.
. Elastic, in which kinetic energy is conserved.
. Inelastic, in which kinetic energy is lost.
. Completely inelastic, in which the objects stick together after the collision.
