Sources of Energy
The energy associated with the motion or the position of a frog as it is leaping
What is Mechanical energy?
To Dribble a basketball
What is Potential to Kinetic?
In an electric circuit the purpose of the output device
What is to change one type of energy to another?
You walk outside on a hot summer day barefoot. You begin to sweat. How is heat transferred?
What is radiation?
This occurs when a force is used to move an object.
What is work?
Green plants use solar energy during photosynthesis to produce sugar, which contains stored
What is Chemical energy?
Eating dinner
What is Chemical to Mechanical or Kinetic?
Solar cells, chemical energy in batteries, fuels in generators
What are sources of electrical energy?
The handle of a spoon in a bowl of soup becomes warm
What is coduction?
Moving this closer to the load can reduce force when using a lever
Visible light, ultraviolet light, or X-rays
What is Radiant energy?
This happens to energy as it is transformed from one form to another
What is the total amount of energy stays or remains the same?
The wire in a circuit
What is a conductor?
Liquids and gases are heated through the movement of particles
What is convection?
This changes only the direction of the force (like a flagpole)
What is a single fixed pulley?
This energy is due to an object's motion
What is kinetic energy?
Water behind a dam that begins to flow
What is Potential to Kinetic?
This circuit allows electricity to flow and the transformer to change electrical energy to another type.
What is a closed circuit?
Heat always moves in this direction
What is from the warmer object to the cooler object?
This can reduce the force is takes to move an object when using an inclined plane.
What is increase the length of the ramp and decrease the angle of the ramp?
This energy is greater when the height or mass of an object is lifted
What is Gravitational Potential energy?
A stretched rubber band is then released
What is Elastic Potential to Kinetic?
This changes electrical energy to mechanical energy
What is a simple electric motor?
This energy is associated with the motion of the particles in a substance.
What is thermal energy?
This can change the efficiency of a wedge.
What is how sharp a wedge is?
