Interpreting Position and Speed Graphs

Interpreting Velocity from position-time graphs

Multiple Choice

Slope of a line is...

• rise over run

• run over rise

• rise x run

Finding velocity from pos vs time graph

• change in position (

   $\Delta d$ ) = rise 

• change in time ( $\Delta t$  ) = run

•  $\frac{rise\ }{run}=\frac{\Delta d}{\Delta t}=slope\ =\ velocity$  

Finding velocity from pos vs time graph

• slope on a position vs time graph = velocity 

Multiple Choice

What is the velocity of the object from 0-5 seconds, based on the slope of the line?

• 5m/s

• 5ft/s

• 1m/s

• 1ft/s

Using Slope to Find Velocity on a Position vs Time Graph

• position is on y-axis = rise

• time is on x-axis = run

• 
  
   $\frac{rise}{run}=\ \frac{\Delta position}{\Delta time}=speed\$
