Energy Forms, Types and Transformation 100 Energy is defined as doing or having the capability of doing this: Work This type of energy includes matter in motion: Kinetic This is the most common form of light energy. Sun 200 This type of energy is gathered as you move to a higher elevation Potential This type of energy is also known as stored energy. Potential Food and gas are examples of this form of energy. Chemical Blowing up a balloon creates this energy form. Elastic energy 300 Energy caused by the vibration or rapid movement of particles in an object Thermal Nuclear energy comes from this part of the atom. Nucleus If a force acts upon an object, and that object moves in the direction of the force, then ___ has been done. Work 400 This converts light energy into food energy. Photosynthesis A unit of thermal energy is a ___________ Joule 500 This form of energy includes radar and x-rays Light This takes up space and has mass. Matter Work has been done if the object moves in the direction of the ___ Force. Energy Efficiency 100 A light bulb has an energy efficiency rating of this percentage. 5% This form of energy is the most common form of non-useful energy in many home appliances. Thermal (heat) 200 Finish this equation: Energy efficiency = what you got divided by ___________ What you paid for This is another name for the conversion of energy from one form to another: Transformation 300 Energy that enters a transformation device is known as this. Input energy Energy that results from a transformation: Output energy 400 Providing light is said to be the __________ purpose of a light bulb. Primary Acid rain is caused by rainwater mixing with ___________ in the atmosphere to create weak carbolic acid. Carbon 500 Finish this equation: Energy efficiency = useful energy divided by _______ x 100 Total energy Newton’s Apples 100 Newton was famous for his research and theories in this field of study. Physics Newton developed and published three laws concerning this subject: Motion 200 According to Newton’s Second Law, Force is a product of mass and this. Acceleration Two forces that act upon a moving object are gravity and ________ Friction 300 According to Newton’s First Law, matter is either in motion or ________ At rest Friction can be increased by adding ______ between the two surfaces. Pressure According to Newton’s Third Law, a balloon releasing energy while it deflates will demonstrate this type of reaction. Equal and opposite 400 According to Newton, Work is the product of Force times _________. Distance This is another name for an object’s resistance to changes in its motion. Inertia A force of 4 Newtons upon a non-moving an object with a mass of 200 kilograms is said to produce this much work None 500 Combined with distance and mass, this factor determines the amount of force of a falling object. Gravity In measuring the kinetic energy of a thrown baseball, one factor is m, or the mass of the ball. The other is known as the letter v, which means Velocity Heat 100 This is known as the transfer of thermal energy from a warmer object to a cooler object Heat Light energy moves through space by this type of heat transfer. Radiation 200 Heat moves through air and water by this type of heat transfer. Convection Heat moves through solid objects by this type of heat transfer. Conduction 300 Heat energy is described using these units of measurement. Joules This type of energy is usually found underground. Geothermal 400 The three stages of a geyser are: heating, erupting and ____________. Refilling This is the name for a material that doesn’t conduct heat well Insulator 500 These are the spaces left between steel rails to prevent deformation of the rails due to heat. Thermal expansion joints A thermometer operates on this principle of thermal energy: Thermal expansion Potpourri 100 These observations are made with the senses. Qualitative These observations have to do with measuring and counting data. Quantitative What is the formula for Force? Force = mass x acceleration 200 Parachutes work on the principle of ______ Air resistance This type of energy is used to pull a bowstring. Mechanical Hydroelectric dams use this type of energy to power its turbines to make electricity. Gravitational 300 Objects entering a body of water will encounter this type of resistance. Fluid friction The point at which air resistance equals gravitational pull of a falling object is called___. Terminal velocity To decrease the amount of force without changing acceleration, this must be decreased. Mass 400 What is the full name of Newton’s Third Law? The Law of Reciprocal Action What kind of output energy is not produced by fish? Heat/Thermal 500 These things determine the flight of an arrow: gravity, air resistance, and force. Name one more. Mass of the arrow An arrow fired at a 40 degree angle will travel a distance equal to an arrow fired at an angle of ___ degrees. Fifty The formula for work is: Work = force x distance
