Let's Get Moving, Pt.1
This is the most fundamental of all sciences
What is physics?
This is defined as a change in position
What is motion?
This is the total distance traveled to the total time of the trip
What is average speed?
This is the rate at which an object is moving at a given moment in time
What is instantaneous speed?
The time rate of change of an object's velocity
What is acceleration?
This is the branch of physics that deals with analyzing and understanding objects in motion
What is mechanics?
A point against which direction is measured
What is a reference point?
Speed is defined as distance divided by this
What is time?
This kind of graph compares constant speeds
What is a distance-time graph?
These are the units of acceleration
What is distance divided by time squared?
This refers to using a reference point to detect motion
What is a frame of reference?
This is the length of a path between two points
What is distance?
The relative speed of objects traveling in the SAME direction is determined by this
What is the difference between speeds?
The relative speed of objects traveling in the OPPOSITE direction is determined by this
What is the sum of individual speeds?
This is the popular yet unscientific way of describing the acceleration that slows the speed of an oject
What is deceleration?
This is the distance an object travels plus the direction from the starting point
What is displacement?
These are physical quantities that carry information concerning direction
What are vector quantities?
The class conducted this many trials in Experiment 6.1
What is 3?
These were rolled to demonstrate the importance of direction in velocity in Exp. 6.1
What are eggs?
This represents accelerated motion on a distance-time graph
What is a curved line?
He posited motion as one of his arguments for God's existence
Who is Thomas Aquinas?
This is what you get when you combine two or more displacement vectors
What is the replacement vector?
This is used to estimate values that are either higher or lower than actual data collected
What is extrapolation?
Speed is indicated by this on a distance-time graph
What is slope?
This determines the acceleration on speed-time graph
What is the slope?
