  1. Population Dynamics • Assumption: The rate at which the population of a country grows at a certain time is proportional to the total population of the country at that time. • DE:

  2. Radioactive Decay • Assumption: The rate at which the nuclei of a substance decay is proportional to the amount of the substance remaining at that time. • DE:

  3. Newton’s Law of Cooling/Warming • The rate at which the temperature of a body changes is proportional to the difference between the temperature of the body and the temperature of the surrounding medium (the ambient temperature). • DE:

  4. Other examples • Spread of Disease/Technology • Mixtures • Draining a Tank • Series Circuits • Falling Bodies and Air Resistance • Newton’s Second Law and Archimedes Principle • Newton’s Second Law and Hooke’s Law • Law of Universal Gravitation
