Mechanical
Mechanical energy is made up of 2 types of energy. What are they?
Kinetic energy and potential energy
Which colors are present in white light?
All the colors of the rainbow
What happens to temperature as molecules move faster
Temperature rises (the faster the molecules move, the more heat the object has)
Which of our senses do we use for sound energy
hearing
When potential energy is high, what happens to potential energy?
Potential energy is low
(Opposite relationship)
Energy that is based on position is called...
Potential energy
What size wavelengths are visible to the human eye?
Medium wavelengths
Convection
What types of matter can sound energy travel through?
Solids, liquids and gasses
In a pendulum, what position has the maximum potential energy?
At the highest point
A child chasing a soccer ball is an example of what type of energy?
Kinetic energy
What is it called when light is bouncing off the surface of an object?
Reflection
Energy Transfer through space that does not require a medium
Radiation
Sound is energy that is felt through what?
Vibrations that travel to your ear
When mechanical energy is not fully transferred, it turns into what 2 types of energy?
Heat and Sound
Potential (stored energy- not yet in motion)
Kinetic (object in motion)
When light energy is absorbed, how is it transferred?
Light energy is transferred as thermal (heat) energy
Energy Transfer through direct contact
Sound waves travel faster through air or water?
Water
What forms of energy are present when you rub your hands together to get warm?
Mechanical (kinetic) energy
Thermal energy (conduction)
(+200 points if you used kinetic and conduction)
How does a wavelength relate to the amount of energy in a wave?
The shorter the wavelength, the more energy the wave contains
When light REFRACTS, what happens to it?
The light bends as it passes through an object
How is Thermal energy produced?
Heat applied to molecules creates movement. The movement creates friction causing thermal energy
How does sound move?
the molecules move from where the sound began. (Like a ripple)
Which types of energy are present when using a blender?
Mechanical
Electrical
Thermal
Sound
