Waves
A wave in which particles of matter move back and forth.
What is a mechanical wave?
A word that describes when an object at rest stays at rest, and an object in motion stays in motion with a constant velocity unless acted on by unbalanced forces.
What is inertia?
The strength of the gravitational force on an object near Earth’s surface depends on the object’s _______.
What is mass?
The way that heat flows.
Where is a region of higher temperature to a region of lower temperature?
An individual particle of an element.
What is an element?
The material, substance, or object that particles travel through.
What is a medium?
An object exerts a force on a second object, the second object exerts a force with equal strength on the first object, but in the opposite direction.
What is Newton's Third Law of Motion?
Objects that have equal numbers of positively charged particles and negatively charged particles.
What is neutral?
The transfer of energy caused by the circulation of matter due to differences in density.
What is convection?
Rohrer and Binnig won a Nobel Prize in 1986 for this probe that exerts an electric current when it is close to an atom.
What is the Scanning Tunneling Microscope?
A wave in which the matter moves in a pattern parallel to the direction that the wave travels.
What is a longitudinal wave?
Forces that have a net force not equal to 0N.
What is an unbalanced force?
This is a change in an object’s speed or direction.
What is acceleration?
Thermal energy is transferred between regions at different temperatures through the collision of particles of matter.
What is conduction?
The location on the periodic table that represents the number valence electrons in an atom?
What is a group (column)?
A wave in which the matter moves in a pattern perpendicular to the direction that the wave travels.
What is a transverse wave?
An object's acceleration is equal to the net force on the object divided by its mass.
What is Newton's Second Law?
The opposition to the flow of electric charge.
What is resistance?
This determines a system’s thermal energy.
What is kinetic energy and potential energy in a system?
A Russian scientist arranged elements into a table with eight vertical columns. He listed them from left to right of the table so that the elements increased in atomic mass.
Who is Dmitry Mendeleev?
The intensity of light or sound depends on this in light and mechanical waves.
What is the amplitude?
A force that opposes the motion between two surfaces that are touching.
What is friction?
A device that uses electric currents to produce motion using permanent magnets and electromagnets.
What is an electric motor?
Three factors that affect thermal energy.
What is the the mass of the matter, the state of the matter, and the type of matter?
This hit the nucleus in the gold foil and it bounced back.
What is an a-particle?
