Energy And Waves Flashcards
Describe kenitic energy
Energy for to and objects motion
Describe light energy
The energy of waves that travel from bright objects
Describe heat energy
Energy caused by vibration of particles
Describe sound energy
Energy produced by vibrating objects such as speakers and bells
Describe electric energy
Energy produced due to the movement of electrically charged particles, found in waves
Describe magnetic energy
Energy stored when magnetic objects are about to move because of attraction or repulsion
Describe gravitational potential energy
Energy stored when an object is night and has the potential to fall
Describe chemical potential
Energy stored in the bonds between atoms and compounds
Describe Elastic potential energy
Energy stored in stretched or squashed object
Describe nuclear energy
Energy stored in the nucleus of an atom
What speed does light waves travel at
299 792 458 m / s
What speed does sound waves travel at
343 m/s
What type of wave is a light wave
Transverse
Can light waves travel through a vacuum
YES
What type of wave is a sound wave
LONGITUDINAL
Can sound waves travel through a vacuum
NO
Define conduction
The process by which heat is transferred from the hotter end to the colder end of an object
Define Convention
The movement caused by within a fluid by the tendency of hotter therefore less dense material to rise, and colder, denser material to sink under the influence of gravity
Define radiation
The transmission of energy in the form of infrared waves
Name the parts of an eye
Iris, lens, cornea, retina, optic nerve
Explain how shadow is formed
A shadow is formed when a opaque blocks light from a light source such as the sun or a lamp as the light hits the object it cannot pass through creating a dark area on the surface behind the object which is a shadow
