First scientist to demonstrate all objects fall at the same rate Galileo Natural selection (evolution) Darwin Proposed the earth travels around the sun Copernicus Discovered the universe is expanding Hubble Developed three laws of motion Newton idea that the laws of physics are the same throughout the universe Universality Logical and orderly methods of solving problems Scientific Method Measure of how much "stuff" an object contains mass Push or a Pull Force LIst the steps to the Scientific Method 1. Problem2. Information3. Hypothesis4. Experiment5. Data6. Conclusion Name 3 characteristics that separate science from non science - If it is real it can be measured- Nature and light change rapidly and often year to year- Knowledge about the universe and methods used to gain knowledge Name Five science process skills 1. Classifying (grouping)2. Communicating (graphs, drawings)3. Controlling variable (fairtest)4. Hypothesizing5. Questioning Energy the ability to do work Work a force moves an object a certain distance What is the formula for work W=FD Work=ForceXDistance Energy is neither created nor destroyed Law of Conservation of Energy First law of Thermodynamics Potential energy energy of position Kinetic energy energy in motion As energy is transferred from one object to another, some energy is "lost" in the form of heat Second Law of Thermodynamics Speed= distance/time Mass matter in an object (kilograms) Weight force of gravity (newtons) Galileo 3 ways to describe motion SpeedVelocityAcceleration Inertia Lazy 1st Law of Motion An object at rest remains at rest 2nd Law of Motion Force= massX acceleration f=ma 3rd law of Motion For every action there is an equal and opposite reaction Authorjilltotten12 ID32268 Card SetScience Test #1 Descriptionscience Updated2010-09-01T20:22:01Z Show Answers
