Position and Velocity
The starting point for measuring position is called what?
Origin
The type of graph that shows speed on the vertical axis and time on the horizontal axis
Speed vs. Time Graph
High acceleration happens when speed changes...
quickly
If an object moves forward 5 meters, how do we state its position as a vector?
+5m
Gravity is represented by the letter...
"g"
Axis
Cause-and-effect relationships can be easily shown on what type of diagram?
A graph
Negative acceleration is when speed is __________ each second
subtracted
If an object moves forward 5 meters, then backward 8 meters, how do we state its position as a vector?
-3m
What vehicle uses position the velocity vector to map its location?
The Mars rover / rovers
Give an example of a vector.
Velocity, acceleration, force, displacement
When data is clumped together so well that a line can be neatly drawn through it
Strong relationship
What is the force of gravity in m/s2?
9.8m/s2
If an object moves forward 6 meters, backward 3 meters, then forward 7 meters, how do we state its position as a vector?
+10m
If the rise is 6 and the run is 2, what is the slope?
Slope = 3
What are the values that give position relative to an origin
Coordinates
What is the ratio of the vertical change over the horizontal change?
Slope
Circular Motion
If an object moves backward 12 meters, forward 9 meters, forward 6 meters, and backward 10 meters, how do we state it position as a vector?
-7m
On a position vs. time graph, a steeper line means...
faster

The formula for calculating slope is what?
Rise / Run
What is the formula for calculating acceleration?
A = ending speed - starting speed / time
