Bell 1 Science 2nd Semester Exam Review

Motion Diagram

• A model of an object that graphs it's motion

• A model of how an object moves by showing its position at various equally spaced amounts of time

• The starting point you choose to describe the location/postion and motion of an object in comparison to; sometimes referred to a reference frame

• The total path an object has traveled given its ending position

Reference Point

• Radioactive particle made of two Protons and two Neutrons repelled by other positively charged particles

• A model of how an object moves by showing its position at various equally spaced amounts of time

• The starting point you choose to describe the location/position and motion of an object in comparison to; sometimes referred to a reference frame

• The weighted average mass of naturally occurring isotopes of each element

Position (x)

• An object’s distance in a certain direction from a reference point

• The center of an atom that contains Protons and Neutrons has the most mass of the entire atom

• The total path an object has traveled given its ending position

• The starting point you choose to describe the location/postion and motion of an object in comparison to; sometimes referred to a reference frame

Distance (d)

• The total path an object has traveled given its ending position

• First to widely recognize the periodic table

  Arranged by atomic mass and properties

• Observed and measured the x-rays of metal crystals

  Found that you could determine the number of Protons in an element

  November 23, 1887 - August 10, 1915

• The starting point you choose to describe the location/postion and motion of an object in comparison to; sometimes referred to a reference frame

Displacement (∆d)

• Each element has a different number of protons

  Determine the type of element

• An object’s distance in a certain direction from a reference point

• A model of how an object moves by showing its position at various equally spaced amounts of time

• The distance between the initial position and the final position of an object; the distance and direction an object has moved 

Scalars

• The rate at which an object moves; the distance traveled over a certain amount of time

• Quantities that can be described by a magnitude (or numerical value) alone

• Quantities that need to be described by BOTH a magnitude and direction

• An object’s distance in a certain direction from a reference point

vectors

• quantities that need to be described by BOTH a magnitude and direction

• quantities that can be described by a magnitude (or numerical value) alone

• the rate at which an object moves; the distance traveled over a certain amount of time

• the force of attraction between all objects in the universe; a natural phenomenon by which all things with mass are brought toward one another

speed (s)

• the rate at which an object moves; the distance traveled over a certain amount of time

• a quantity, amount, or degree of something measured per unit of something else; written as a fraction

• the speed of an object in a specific direction; the displacement of an object over a certain amount of time

• a relationship between variables where an increase in one quantity leads to a corresponding increase in the other; makes a straight line on a graph

Rate

• a quantity, amount, or degree of something measured per unit of something else; written as a fraction

• the rate at which an object moves; the distance traveled over a certain amount of time

• the force of attraction between all objects in the universe; a natural phenomenon by which all things with mass are brought toward one another

• the speed of an object in a specific direction; the displacement of an object over a certain amount of time

Velocity (v)

• the speed of an object in a specific direction; the displacement of an object over a certain amount of time

• the rate at which an object moves; the distance traveled over a certain amount of time

• a quantity, amount, or degree of something measured per unit of something else; written as a fraction

• the force of attraction between all objects in the universe; a natural phenomenon by which all things with mass are brought toward one another
