The Commotion About Motion
A change in an object's position relative to a reference point
What is motion?
Draw a Distance vs. Time graph showing an object that is stopped (at rest / no motion) for 5 seconds.
What is a graph with a flat, horizontal line?
The type of measurement represented by "2,000 meters" or "2.9 miles."
What is Distance (D)?
If a car drives from Greensboro to Raleigh at a faster speed, this is what happens to the travel time.
What is it decreases (takes less time)?
On a Distance vs. Time graph, a flat, perfectly horizontal line represents this type of motion
What is no motion (stopped / at rest)?
A stationary place or object used for comparison to determine if something is in motion.
What is a reference point?
Draw a Distance vs. Time graph showing a jogger moving away from the starting line at a constant speed for 3 minutes.
What is a graph with a straight line sloping upwards from the origin (0,0)?
The type of measurement represented by "5.5 hours" or "9,999 seconds."
What is Time (T)?
The key characteristic that makes an object a good reference point.
What is being stationary (fixed in place / not moving)
On a Distance vs. Time graph, the visual feature of a line that tells you an object is moving FASTER than another.
What is a steeper slope (or steeper line)?
This measurement is defined as the distance an object travels per unit of time
What is speed?
Draw a Distance vs. Time graph showing Sam walking to school, stopping at a bench to rest for 2 minutes, and then continuing his walk to school at the same speed
What is a line sloping upward, transitioning into a flat horizontal line, and then sloping upward again?
The type of measurement represented by "89 mi/hr" or "9 m/s."
What is Speed (S)?
The 3 distinct ways an object can undergo acceleration.
must have all 3 to receive the points!
What are speeding up, slowing down, or changing direction?
On a Distance vs. Time graph, a line that slopes downward back toward the x-axis indicates this motion
What is returning to the starting point?
Unlike speed, this measurement describes both an object's speed and its specific direction of travel
What is velocity?
Draw a Distance vs. Time graph showing a runner traveling 50 meters away from the start line in 10 seconds, and then running back to the starting line in 10 seconds
What is a line sloping upward to 50 meters, followed immediately by a line sloping downward back to the x-axis?
The type of measurement represented by "67 mi/hr North" or "25 inches/second Right."
What is Velocity (V)?
How two runners moving at the exact same speed of 13 mph can have completely different velocities.
How is running in different directions?
On a Distance vs. Time graph showing two joggers over 10 minutes, the jogger who covers more total vertical distance reached this outcome
Who ran a farther distance?
The term used to describe any rate of change in velocity or speed over time.
What is acceleration?
Draw a Distance vs. Time graph containing two lines: Line A representing a fast car and Line B representing a slow car starting at the same time.
What is a graph showing two straight lines where Line A has a significantly steeper slope than Line B?
The single property that transforms a measurement of speed into a measurement of velocity.
What is direction?
How an ice skater moving around a circular rink at a constant speed of 15 mph is still accelerating.
What is she is constantly changing her direction?
On a Distance vs. Time graph, if Kathy reaches 300 meters in 3 minutes, this is her calculated constant speed.
What is 100 m/min?
