No calculators allowed! 1. Take 1000 and add 40 to it. Now add another 1000. Now add 30. Add another 1000. Now add 20. Now add another 1000. Now add 10. What is the total? 4100 2. If you overtake the second person in a race, what position would you be in? Second Brain Teasers 3. If you overtake the last person in a race, what position would you be in? It is not possible 4. What is 192 + 192 - 192 times 192 divided by 192? 192 5. Some months have 31 days. How many have 28? All of them 6. Divide 30 by ½ and add 10. 70 What is physics? • Physics is the most basic of all sciences. • It is about the nature of basic things such as motion, forces, energy, matter, heat, sound, light, and the structure of atoms. • Physics is a way we search for ways to explain, simplify, and predict phenomena in the natural world. What is physics? Give two examples WITHOUT SAYING THE RULE • It is off but not on • It is cool but not cold • It is kitten but not cat • It is wall but not ceiling • It is Milwaukee but not Chicago • It is Illinois but not Wisconsin • It is nineteen but not twenty • It is three but not two • It is pepper but not salt • It is book but not text • It is tall but not short • It is knee but not elbow What is physics? • Physics consists of a set of rules that govern the world around us. 7 Branches of Physics Mechanics Motion and its causes, interactions between objects Thermodynamics Heat and temperature Vibrations and wave phenomena Specific types of repetitive motions – springs, pendulums, sound Optics Light, including mirrors, lenses, color Electromagnetism Electricity, magnetism, and light, including electrical charge, circuits, and magnets Relativity Particles moving at any speed, including very high speed Quantum mechanics Behavior of submicroscopic and subatomic particles
