Graphically Representing Motion Displacement vs. Time graphs Velocity vs. Time graphs

Recall: Displacement vs. Time Graphs DO NOW: describe the motion represented in each graph AB C D EF d t d t d t d t d t d t

New: Velocity vs. Time Graphs A B v t v t

C v t D v t

AIM: How do we interpret motion graphs? Do Now: 1.What is the slope of a distance vs. time graph? 2.What is the slope of a velocity vs. time graph? Classwork/HW Blue Work Book Pg #15-40

Motion Graph 1 Verbally describe the motion for each section of the graph Distance (m) Time (s)

Motion Graph 1 Verbal Description (include position, distance covered, velocity, direction and time period) Total Distance Traveled – Total displacement – Average speed – Average velocity –

Motion Graph 2 Verbally describe the motion for each section of the graph velocity (m/s) Time (s)

Motion Graph 2 Verbal Description (include position, distance covered, velocity, acceleration direction and time period) Total Distance Traveled – Total displacement – Average speed – Average velocity –

Motion Graph 3 Sketch the motion on a displacement vs. time graph A child starts 3 meters to her mother’s left and remains there for 3 seconds. The child then crawls towards the mother at a rate of 0.5m/s for a total of 4 seconds. The child then remains stationary for another 3 seconds and then crawls away from the mother covering 3meters in 3 seconds.

displacement (m) Time (s)

Motion Graph 4 Sketch the motion on a velocity vs. time graph A car initially travels north at 5m/s for 3 seconds. The car then constantly slows to a stop over 5 seconds and remains stationary for 3 seconds. The car then turns around and accelerates at a rate of 0.5m/s 2 for 4 seconds and remains at that constant speed for 4 seconds. The car then uniformly slows to a stop over the remaining 4 seconds.
