Module 4 - Momentum and Energy#

yoyo despin

This module uses energy and momentum methods directly.

  1. Energy and Momentum are different forms of Newton’s second law

    1. Impulse-momentum is Fdt=dp

    2. Work-energy is Fdx=dT

    3. momentum is a vector

    4. energy is a scalar

  2. Describes states of system

  3. Impulse happens over short time in impact

  4. energy in conservative system ia conserved

  5. combining methods
