(50 cards)

Reflection

Front

A wave bouncing off an object

Back

Mechanical

Front

Requires a medium to travel through Ex) ocean waves, earthquakes, waves on a string

Back

Which end of the EM Spectrum has the lowest frequency?

Front

Radio waves

Back

Newton's 3rd Law

Front

Equal and Opposite - Every applied force has an equal and opposite reaction force

Back

Electromagnetic Waves

Front

Do not require a medium to travel through Ex) radio waves, microwaves, gamma rays

Back

Free Body Diagrams

Front

A diagram that describes all forces acting on an object Lengths of arrows represent the strength of the force All forces drawn out from one point

Back

If a moving source of waves is coming towards you, what sort of shift in frequency would you observe?

Front

An increase in frequency

Back

What is the order of the waves on the EM spectrum from longest to shortest wavelengths?

Front

Radio waves Microwaves Infrared Radiation Visible Light Ultraviolet X-Rays Gamma Rays

Back

Refraction

Front

A wave bending through an object

Back

Scalar

Front

Has magnitude only

Back

Convection Currents

Front

Warmer gas/liquid is less dense, so it rises. As it rises it cools back down and becomes more dense. As it becomes more dense it sinks back down.

Back

Parts of the wave

Front

Wavelength, Amplitude, Line of Equilibrium, Crest, Trough

Back

Amplitude

Front

Distance from line of equilibrium to crest or trough

Back

Typical Forces Used

Front

Force due to gravity (Fg) Normal Force (FN) Applied Force (Fapp) Friction Force (Ff) Tension Force (FT)

Back

Convection

Front

Heat transfer through gases and liquids

Back

Kinetic Energy

Front

Energy that comes from being in motion

Back

Temperature

Front

The average kinetic energy of particles in an object

Back

Frequency

Front

Number of cycles per second

Back

Examples of Scalars

Front

Distance, Speed, Mass

Back

Trough

Front

Bottom point of wave

Back

Longitudinal Waves

Front

Energy moves parallel to the motion of the particles

Back

What changes it state cause the energy of the particles to increase?

Front

solid to liquid to gas

Back

Which end of the EM Spectrum has the highest energy?

Front

Gamma Rays

Back

Wavelength

Front

Distance from crest to crest or trough to trough

Back

Does a mechanical wave move faster through a solid or a liquid?

Front

Solid

Back

Crest

Front

Top point of wave

Back

Momentum

Front

mass in motion Always conserved

Back

If a moving source of waves is moving away from you, what sort of shift in frequency would you observe?

Front

A decrease in frequency

Back

Newton's 1st Law

Front

Law of inertia - an object at rest will stay at rest and an object in motion will stay in motion until acted upon by an outside, unbalanced force

Back

Thermal Equilibrium

Front

Objects that are in contact with each other are the same temperature

Back

Work

Front

Work is done when an object is in motion due to a force

Back

Doppler Effect

Front

The effect produced by a moving source of waves where there is an observed shift in frequency

Back

Sine

Front

Opposite/Hypotenuse

Back

Line of Equilibrium

Front

Center line of wave - point of no displacement

Back

Newton's 2nd Law

Front

F=ma The force is directly proportional to both the mass and the acceleration of the object

Back

Potential Energy

Front

Energy that an object has based on its position relative to other objects

Back

Transverse Waves

Front

Energy moves perpendicular to the motion of the particles.

Back

Examples of Simple Harmonic Motion

Front

A person on a seesaw A person on a swing A pendulum swinging

Back

Medium

Front

Some substance that waves can travel through Ex) water, string, air

Back

Conservation of Energy

Front

Energy cannot be created nor destroyed

Back

Does heat transfer from hot to cold or cold to hot?

Front

Hot to cold

Back

Radiation

Front

Heat transfer through a vacuum. How we get heat from the sun

Back

Tangent

Front

Opposite/Adjacent

Back

Simple Harmonic Motion

Front

Something that moves equal distances away from the equilibrium line in both directions

Back

Vector

Front

Has magnitude (size) and direction

Back

Period

Front

Time it takes for one cycle

Back

Conduction

Front

Heat transfer between objects that are touching

Back

Cosine

Front

Adjacent/Hypotenuse

Back

Examples of Vectors

Front

Displacement, Velocity, Acceleration, Force, Momentum

Back
