An object distance from another object is changing
What is motion?
These kind of objects make good reference points.
What are stationary objects?
More than a dozen of these make up earth’s outer layer
What are plates?
The rate at which velocity changes.
What is acceleration?
Steepness of a line that shows the rate of change
What is slope?
Distance the object travels per unit of time
What is speed?
Plates move very what?
What is slowly?
When you are slowing down, it is known as what?
What is deceleration?
Speed of an object in a given direction
What is velocity?
Basic unit of length
What is the meter?
These are cracks in the Earth's outer layer but don't always lie along the continental edge.
What are boundaries between plates?
Riding down a hill is an example of acceleration or decceleration?
What is acceleration?
A place or object used for comparison to determine if something is in motion
What is a reference point?
Motion can be graphed with a line graph showing the rate of change between what two things.
Distance and time
These are the two types of plates
Continental and Oceanic
A car stopping at a red light is an example of acceleration or decceleration?
Deceleration
To find what type of speed would you divide total distance traveled by the total time.
What is average speed?
The rate at which an object is moving at a given instant rate
What is instantaneous speed?
This theory states that Earth’s plates move slowly in various directions.
What is the Theory of Plate Tectonics?
The equation for finding acceleration.
final speed-initial speed divided by time
