Presentation on theme: "Motion Graphs. Position is on the vertical axis Time is on the horizontal axis Slope (rise/run or Δy/Δx) = velocity A curved graph shows acceleration."— Presentation transcript:
Velocity is on the vertical axis Time is on the horizontal axis Slope is acceleration Area between the graph and the time-axis is displacement Use triangles and rectangles to find the area
velocity time A ball thrown up in the air (initial +v), slowing down, stopping at it’s peak (zero velocity), and coming back down (-v). Constant negative acceleration.
Determine the displacement from 2 to 5 seconds. velocity time 50 m/s 5 sec 2 sec 20 m/s
acceleration time (sec) 2 m/s 2 -4 m/s 2 502080 A car is moving with a constant acceleration of +2 m/s 2 for 20 seconds and then travels at a constant velocity for 30 seconds and then travels with a constant acceleration of -4 m/s 2 for 30 seconds.
