Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

• is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation

What is the difference between Potential and Kinetic Energy?

• Potential Energy is moving and Kinetic Energy has the potential to move.

• Potential is the energy a object has in motion, and Kinetic Energy is moving energy.

• Kinetic is energy in motion and Potential energy is waiting to move.

• Kinetic Energy is based on gravity and potential is based on motion

A spoon is placed in hot soup and becomes warm.  How is heat transferred?

• Convection.  The soup swirls around the spoon.

• Radiation.  The heat given off to the spoon makes it hotter.

• Conduction.  The spoon transfers the cold to the hot soup?

• Conduction.  The heat is transferred to the spoon by contact.

What is Newton's 3rd Law of Motion?

• For every action there is an equal but opposite reaction.

• The more force applied, the greater the acceleration.

• The object in motion remains in motion unless an unbalanced force acts on it.

• It is the Law of Inertia
