100
This allows you to exert your input force over a longer distance.
What is an inclined plane.
100
This is the ability to do work or cause change.
What is energy
100
This is something done on an object when the object moves in the same direction in which force is exerted.
What is work
100
This is the way one form of energy changes another.
What is an energy transfer.
100
This is temperature.
What is the measure of the average kinetic energy of individual particles in an object.
200
This is a type of inclined plane that moves.
What is a wedge.
200
Name the two basic kinds of energy.
What are kinetic and potential.
200
This is the equation to determine the amount of work done on an object.
What is work=force x distance
200
This is the most common form of energy transformation.
What is the transformation between potential energy and kinetic energy.
200
These are the 3 common scales for measuring temperature.
What are Fahrenheit, Celsius, and Kelvin.
300
Name 3 real life example of a wheel and axel.
What is a fan, wheels on a car or a bike, pencil sharpener, windmill.
300
Define thermal energy.
What is the total potential and kinetic energy of the particules in an object.
300
This is a device that changes the amount of force exerted, the distance over which a force is exerted, or the direction in which the force is exerted.
What is a machine
300
This states that when one form of energy is transformed to another, energy is neither created nor destroyed.
What is the law of conservation of energy
300
These are the 3 forms of heat transfer.
What are conduction, convection and radiation.
400
This is a device that combines two or more simple machines.
What is a compound machine.
400
This is the unit energy is measure in.
What are joules
400
Something that equals the ratio of the output force to the input force.
What is a mechanical device.
400
These contain energy that ultimately came from the sun.
What are fossil fuels
500
Name all 6 basic types of simple machines
What are the inclined plane, wedge, screw, lever, wheel and axel, and the pulley.
500
Name the 4 other energy types that are associated with the particles of objects.
What are electrical energy, chemical energy, electromagnetic energy, and nuclear energy.
500
This is the efficiency of a machine.
What is the percentage of the input work that is converted to the output work.
500
This is a rapid reaction between oxygen and fuel that results in fire.
What is combustion
500
This is a consequence if a substance has a high specific heat.
What is that it can absorp a great deal of thermal energy without a great change in temperature, which requires a lot of energy.
