Heat and Temperature. Temperature. Temperature measures the “speed” of the molecules Celsius Scale 0 0 C water freezes, 100 0 C water boils Fahrenheit Scale 32 0 F water freezes, 212 0 F water boils Kelvin Scale 0 K 273 0 K water freezes, 373 0 K water boils ABSOLUTE Zero 0 0 K.

When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. Arthur C. Clarke, Clarke’s First Law.

Sir Francis Galton. Coined the term in 1883, from Greek “well born” Cousin of Charles Darwin Concluded that traits like intelligence were inherited. Positive Eugenics. Humans should be bred to improve the species Encourage ‘most fit’ to reproduce Better Babies Contests

Physics I Class 03. Newton’s Laws of Motion. Important Notice. Newton’s Laws of Motion. What is a Force?. Forces Are Vectors - Adding Force Vectors. Newton’s First Law. Newton’s Second Law “F = ma”. Using Newton’s Second Law to Solve Problems. Free-Body Diagrams.

The story so far…. Position tells you where you are Velocity tells you change in position with time Acceleration is the change in velocity with time These properties have magnitude and direction Now What causes an object to change its velocity?

Chapter 5: Newton’s Laws: Force and Motion. 5.1 The First Law: Force and Inertia 5.2 The Second Law: Force, Mass and Acceleration 5.3 The Third Law: Action and Reaction. Chapter 5 Objectives. Describe how the law of inertia affects the motion of an object.

From Aristotle to Newton: A Revolution in Science. Setting the Scene: Philosophy of the Time. The heavens represent perfection. The heavens are immutable. The circle is the perfect shape. All heavenly motions must be circular. The earth is at the center of the universe.

Force and Newton’s Laws of Motion. BY: BRIANNA SHIELDS. DO NOW. 1. If a foam block and a brick are dropped from the roof of the school, which one will hit the ground first? 2. Where on Earth could you go to weigh the most?

Thermodynamics and Statistical Mechanics. Spring 2006. Thermodynamics. Thermodynamics is an old science, formulated empirically without reference to atoms or molecules. It deals with energy, as does mechanics, but adds some new quantities, besides work, potential energy and kinetic energy.

Chapter 5 Ground Rules of Metabolism Sections 1-5. Energy. We define energy as the capacity to do work One form of energy can be converted to another Familiar forms of energy include light, heat, electricity, and motion ( kinetic energy )

Absolute Zero. Physics 313 Professor Lee Carkner Lecture 15. Exercise #14 Carnot Cycle. Isothermal heat = work W = (1.5)(8.31)(700)ln(2X10 -3 /4X10 -4 ) Net work depends of efficiency h = W/Q H = 0.6 Can get output heat from first law Q L = Q H - W = 14043-8426 = 5617 J.
