Conservation of Momentum • Principle that states that the total momentum of an isolated

Conservation of Momentum • Principle that states that the total momentum of an isolated system stays constant. – Total momentum before a collision equals total momentum after a collision p = 30 kg·m/s p = 20 kg·m/s Total = 50 kg·m/s p = 20 kg·m/s p = 30 kg·m/s Total = 50 kg·m/s

Conservation of Momentum • Principle that states the total momentum of an isolated system

Conservation of Momentum • Principle that states the total momentum of an isolated system stays constant p = 40 kg·m/s p = 20 kg·m/s Total = 60 kg·m/s

worksheet • In elastic collisions, the objects bounce after colliding. • In inelastic collisions,

worksheet • In elastic collisions, the objects bounce after colliding. • In inelastic collisions, the objects stick after colliding. • The law of conservation of momentum states that the total momentum before a collision is equal the total momentum after a collision.

ENERGY CONVERSIONS Energy Transformation A change from one form of energy to another is

ENERGY CONVERSIONS Energy Transformation A change from one form of energy to another is called an energy conversion. Any form of energy can be converted Into any other form of energy.

CHEMICAL ENERGY CONVERSIONS 1. Chemical energy in food is converted to ……… 2. Mechanical

CHEMICAL ENERGY CONVERSIONS 1. Chemical energy in food is converted to ……… 2. Mechanical energy when you are moving, 3. Heat as a result of the movement to maintain body temperature (homeostasis) I think therefore I convert energy Chemical mechanical thermal (heat)

CONSERVATION OF ENERGY The Law of Conservation of Energy states that when one form

CONSERVATION OF ENERGY The Law of Conservation of Energy states that when one form of energy is converted into another form of energy, no energy is destroyed in the process. Energy cannot be Created or Destroyed.
