100
a variable that gives your location relative to an origin
What is position?
100
the speed that stays the same and does not change
What is constant speed?
100
the rate at which velocity changes
What is acceleration?
100
a variable that tells you both speed and direction
What is velocity?
100
__________ acceleration is when speed increases each second.
What is positive?
200
a place where the position has been given a value of zero
What is origin?
200
a mathematical diagram showing one variable, the vertical (y-axis) and the second variable, the horizontal (x-axis).
What is a graph?
200
accelerated motion that happens when an object falls with only the force of gravity acting on it
What is a free fall?
200
one of two (or more) number lines that form a graph
What is an axis?
200
___________ acceleration is when speed decreases in one direction.
What is negative?
300
describes how quickly an object moves, calculated by dividing the distance traveled by the time it taks
What is speed?
300
in an experiment, a variable is changed by the experimenter and causes the changes in the dependent variable
What is an independent variable?
300
the value of 9.8m/s2, which is the acceleration in free fall at Earth's surface, usually represented by the lowercase letter, g
What is acceleration due to gravity
300
values that give a position relative to an origin
What is coordinates
300
an accelerated motion that happens when an object falls with only the force of gravity acting on it
What is a free fall?
400
the total distance divided by the total time for a trip
What is average speed?
400
in an experiment, a variable that responds to changes in the independent variable
What is dependent variable?
400
an object moving through space and affected only by gravity
What is a projectile?
400
? = Vfinish-Vstart/time
What is acceleration?
400
kicking a soccer ball is an example of a _______ motion
What is a curve?
500
the actual speed of a moving object at any moment, often changes constantly
What is instantaneous speed?
500
the ratio of the rise (vertical change) to the run (horizontal change) of a line on a graph.
What is a slope?
500
a variable which gives direction information included in its value
What is a vector?
500
?= distance/time
What is speed?
500
