Chapter 9- Motion Flashcards
Constant acceleration
All points fit on the best fit line
Average acceleration
If all of the velocities do not fit in the best for line
Velocity-time graph
Can be analyzed to describe the motion of an object
Pos slope- objects velocity is increasing in pos direction
Zero slope- objects velocity is constant
Neg slope- objects velocity is decreasing in positive direction or increasing in neg direction
SI unit of acceleration
2
m/s
2
Or km/h
Slope
Rise over run or
Change in velocity over change in time
Gravity
Is the pulling force that acts between two or more masses
The acceleration due to gravity is 9.8 m/s downward
Slope of line
Acceleration
A line above x-axis
Positive velocity
A line below x-axis
Negative acceleration
A line with pos slope
Pos acceleration
A line with neg slope
Negative acceleration
A horizontal section of the graph
Constant velocity or zero acceleration
A point where line crosses the x- axis
Zero velocity
Velocity-time graph
Represents the motion of an object with a changing velocity
