Chapter 2 Test Flashcards
Particle model
Replace the object of interest with single points
Motion diagram
Series of images showing the positions of a moving object at equal time intervals
Coordinate system
Gives you the location of the zero point of the variable you are studying and the direction in which the values of the variable increase
Origin
Point at which all valuables in the coordinate system have the value zero
Position
He distance and direction from the origin to the object
Distance
Total length of an objects path
Magnitude
Size
Vector
Both magnitude and direction
Scalar
Just a number and no direction
Time interval
Difference between two times
Displacement
Change in position
Resultant
Vector that replaces the sum of two other vectors
Position time graph
Time data plotted on horizontal axis and position data on the vertical axis
Instantaneous position
Position at a particular instant
Average velocity
Quotient of an objects change in position divided by the time interval during which the change occurred
