100
term that refers to in comparison to a reference point
What is "relative to"?
100
speed and direction
What is velocity?
100
Acceleration calculates for
What is change in velocity? or
What is change in speed and/or direction?
100
The kind of graph represents speed using linear functions
What are distance-time graphs, the two measurements compared are distance and time.
100
Describe your position relative to a reference point.
What is
answers vary?
200
A complete description of a position includes...
What is a reference point and a reference direction?
200
Define speed and units of speed.
What is...
In some cases you might move faster or slower than other times. One way you can describe how fast you move is to determine your speed. Speed is a measure of the distance an object travels per unit of time.

200
Identify and explain the three factors that can affect acceleration.
What is speeding up, slowing down, and changing direction?
200
What kind of graph shows rates of acceleration through linear functions?
What is speed-time graphs?
or
What is velocity-time graphs?
200
Use the term 'positive' in two different contexts.
What is..
an object experiences positive acceleration when it speeds up and does not change direction
one can move positively when we move towards a specified reference direction,
300
Define dimensional instruction.
What is dimension is linear and refers to the direction. If you only walked the direction, left to right, then that instruction is only one dimensional. 2-Dimensional instructions use two perpendicular directions.
300
does not have a rate of speed.
What is a changing speed?
300
the formula for acceleration
What is change in velocity divided by change in time?
300
Constant speed and no acceleration are represented on both distance-time and speed-time graphs. Show how you would represent this on both graphs.
What is constant speed is represented by a diagonal line on a distance-time graph. No acceleration is represented on a speed-time graph by a horizontal line.
300
Identify and explain how the terms 'positive' and 'negative' are used in reference to acceleration.
Explain how it is different in relativity to reference points/directions.
What is...
In the context of acceleration, a positive acceleration is speeding up in the same direction. So for example if an object is traveling towards the east and it speeds up but doesn’t change direction, that is positive acceleration. Any object in motion that slows down or changes direction is experiencing negative acceleration.
In relation to acceleration, the terms relate to a specific concept rather than with reference points/directions where they did not have a specific meaning unless one was assigned.
400
Compare and Contrast:
Displacement vs. Distance. Give an example and define both terms.
What is...
Distance depends only on the path taken. Displacement depends only on the initial and final position.
Example:
Baseball field, swimming laps, etc.
400
Identify and explain three types of speed.
What is...
Constant speed is the rate of the change of position in which the same distance is traveled within each unit of time.
Does not change
Instantaneous speed is the speed rate at a specific instant in time.
Between 0s and 2s, the car travels 10m.
Average speed is total distance traveled divided by the total time taken.
400
What is the triangle in the acceleration formula called?
What is delta?
400
Describe an occasion in which the same linear function means two different things on the two graphs we have learned about.
What is a diagonal line means constant speed in a distance-time graph while it means a positive acceleration on a speed-time graph?
400
Give an example of a 2-dimensional set of instructions to get to one position.
What is..

Explain how motion is relative. Use at least one example.
What is motion is relative to the reference point. (see example, man on the boat).
The man in the boat is not in motion compared to his fishing, but the man in the boat is not in motion compared to the buoy.
500
Compare and Contrast:
How are average speed and displacement alike?
What is they both calculate the starting and ending point.
500
Define how negative and positive acceleration differ. Give at least one example.
What is in the context of acceleration, a positive acceleration is speeding up in the same direction. So for example if an object is traveling towards the east and it speeds up but doesn’t change direction, that is positive acceleration. Any object in motion that slows down or changes direction is experiencing negative acceleration.
500
Describe motion in each one of the following graphs.
What is
an object in motion is slowing down towards an eventual rest while in the other graph the object in motion is lowering its speed and coming to a complete stop.
In this case these graphs represent almost the same motion of an object.
