What describes the thermal energy of particles in a substance?
the higher the temperature: the more the movement of energy in the particle. the lower the temperature: the less the movement of energy in the particle.
The energy of a sound wave relates to its?
it relates to amplitude
How can the work-kinetic energy theorem explain why the force of sliding friction reduces the kinetic energy of a particle?
Work = change in Kinetic Energy Because friction acts in the opposite direction of the motion of an object, kinetic energy must be decreased in order to maintain the above equation. Friction opposes motion. Friction converts the kinetic energy of a particle into heat and sound.
How is particle movement related to thermal energy?
when a particle moves it rubs against other particle's causing thermal energy
What term is used to describe the fact that electromagnetic radiation can be thought of as either a continuous wave or as a stream of individual packets of energy?
wave-particle duality
Which direction is the particle motion in shear waves relative to the energy of the wave?
The particle motion in shear waves relative to the energy of the wave is downward.
How would you describe the action of cool particles?
The colder a particle is, the less energy it has and the slower it moves.
What describe the kinetic energy of a particle?
kinetic energy is the energy that a particle has obtained due to its motion.It mainly depends upon the mass of the body and its velocity. kinetic energy is mathematically calculated as (0.5 x mass of the body x square of its velocity)
What is Einsteins famous equation E equals mc2 what does it calculate?
It relates the energy of a particle to it's mass. So, if you were to convert 1kg of material into pure energy, the energy you would get out would be calculated using E = mc2.However, this is just the simplified version for a particle that isn't moving. If the particle is moving with a momentum p, then the full formula is used: E2 = p2c2 + m2c4.
describe the longitudinal nature of sound waves?
waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport.
What describes the thermal energy of particles in a substance?
the higher the temperature: the more the movement of energy in the particle. the lower the temperature: the less the movement of energy in the particle.
The energy of a sound wave relates to its?
it relates to amplitude
How is energy related to particle movement?
when a particle moves it rubs against other particle's causing thermal energy
How would you describe the change in the arrangement of particle as heat energy and temperature increase?
they get less dense, more spaced, get more active
How are sound waves and electromagnetic waves different from one another?
Electromagnetic waves are transverse waves I.E the direction of movement of each particle in the medium is perpendicular to the direction of the transfer of energy, similar to a water wave. Sound waves are transverse and so the direction of the movement of the particles in the medium is the same direction as the movement of the energy.
What causes radiation pressure?
radiation light has energy and direction. Energy can be describe as having mass. E=mc2 Therefore all light can exert a pressure on objects dependent on its vector direction.
How can the work-kinetic energy theorem explain why the force of sliding friction reduces the kinetic energy of a particle?
Work = change in Kinetic Energy Because friction acts in the opposite direction of the motion of an object, kinetic energy must be decreased in order to maintain the above equation. Friction opposes motion. Friction converts the kinetic energy of a particle into heat and sound.
