Atomic Anatomy
This subatomic particle determines the unique chemical identity of an atom
Proton
A flat, horizontal line on a position vs. time graph indicates this about an object's velocity.
What is 0 m/s (at rest)
Unlike speed, velocity includes this additional critical piece of measurement
Direction
A driver and a dog sitting in a moving Jeep are NOT moving relative to each other, but ARE moving relative to these roadside objects.
What are palm trees
True or False: Neutrons have a positive electrical charge.
False (they are neutral)
In a Bohr model of an atom, electrons should be drawn on these lines surrounding the central nucleus.
Orbitals (or Shells)
On a distance-time graph, a steeper slope represents a greater value for this measurement.
Speed ( Or Velocity)
According to Newton's First Law, an ice skater who pushes off will continue sliding until this acts on them.
What is an unbalanced force
If a cat runs North toward Rabbit 1 while Rabbit 2 holds still, Rabbit 2 appears to move in this direction relative to the cat.
South
On a position vs. time graph, points spaced farther apart over equal 5-second intervals indicate the object is traveling at a higher ____
Speed
These two subatomic particles are located together inside the nucleus at the center of an atom.
protons and neutrons?
An object moving with uniform, constant speed is represented on a velocity vs. time graph by this type of line.
horizontal line
This force opposes motion and acts to slow down moving objects sliding across a surface.
Friction
To determine if an object is in motion, its position must change relative to this chosen point of comparison
frame of reference (or reference point)
An atom containing 6 protons, 6 neutrons, and 6 electrons represents an atom of this element.
Carbon
This subatomic particle carries a negative charge and has far less mass than protons or neutrons
Electron
A line curving upward on a distance vs. time graph indicates that the object is doing this.
What is accelerating (speeding up)
his fundamental property keeps an object steady, whether at rest or moving at a constant velocity.
What is inertia?
If Runner M is faster than Runner O, Runner M's line on a position-time graph will have a slope that is ____ than Runner O's.
What is steeper
A flat segment in the middle of John's distance-time graph on his walk to school could mean he was doing this.
waiting at a crosswalk/stopped
To calculate the number of neutrons in a neutral carbon atom (Carbon-12), you subtract the atomic number (6) from this value (12).
atomic mass (6 neutrons)
On a coordinate reference frame, a coordinate value of $-2\text{ cm}$ uses the negative sign to indicate this
What is direction relative to the origin
If a go-cart accelerates up to $40\text{ m/h}$ and then maintains a constant speed, its velocity-time graph becomes horizontal at this speed value
What is 40 m/h
If an insect walks quickly, stops briefy, walks slowly, and then speeds up, a flat section on its distance-time graph represents the time when it was doing this.
Stopped ( at rest)
A line slanting rapidly upward on a velocity vs. time graph indicates rapid ____.
acceleration
