Can we discuss common graph questions that we can expect on the AP test?
Sure!
There are a few very common graphs that you might see on the exam:
- position vs time - x vs t, h vs t, \theta vs t
- Slope = velocity (or \omega for \theta vs t)
- Curved Slope = Accelerating,
*Concave up = positive accel.
*Concave down = negative accel.
- Curved Slope = Accelerating,
- Slope = velocity (or \omega for \theta vs t)
- velocity vs time (or \omega vs time for rotational)
- Slope = acceleration (or \alpha)
- Area = change in position (displacement)
- Force vs Time
- Area = Impulse (Change in Momentum)
- Force vs Displacement
- Area = Work done on the object (change in Energy)
- Energy Graphs
- If Energy vs position - PEg is linear, PEs is polynominal (PE_s = 1/2kx^2)
Hope this helps!
