Unit 2: Momentum and Energy
All moving objects have momentum and energy. These two quantities have the
priceless property of being conserved. Examining these quantities
gives us more tools to analyse how objects move and interact with other objects.
This is fundamental to the study of collisions, gases, and astronomical phenomena.
By the end of this unit the
student will be able to:
- solve collision problems using conservation of momentum,
in 1 and 2 dimensions
- define and use impulse in problems (impulse is a minor
- define elastic collision
- determine the percent of kinetic energy lost in inelastic
- use special formulas for elastic collisions in one
- use Hooke’s law to find the spring constant
- use kinetic energy, gravitational potential energy,
elastic potential energy and the conservation of energy to solve
problems (springs, oscillators, ...)
- write the equations for x, v, and a for a simple harmonic
- find the frequency and period of oscillators
- Most of the information in this unit was originally from
