To get reminders from me…. Answers to the Chapter 1 assignment are on my website under AP Physics Diary. F ill in the table below:. Fill in the table below:. p-t graphs v-t graphs. If you calculate the slope ( Δ X/ Δ t) you get the average velocity.

p-t graphs v-t graphs • If you calculate the slope (ΔX/Δt) you get the average velocity. • If the slope is constant, the velocity is constant. • For an increasing or decreasing slope, you can calculate the slope of the line tangent to the curve to get the instantaneous velocity. • If you calculate the slope (Δv/Δt) you get the average acceleration. • If the slope is constant, the acceleration is constant. • For an increasing or decreasing slope, you can calculate the slope of the line tangent to the curve to get the instantaneous acceleration. • If you calculate the area under the line (Δv x Δt) you get the displacement (ΔX)
Graph trials A-D together: Trial A: Student walks at a constant velocity from the 0 yard to the 50 yard line. Trial B: Student walks at a constant velocity but faster than trial one from the 0 yard to the 50 yard line. Trial C: Student jogs at a constant velocity from the 0 yard to the 50 yard line. Trial D: Student starts at 50 yard line and walks at a constant velocity toward the 0 yard line.
Graph trials E-F together: Trial E: Student starts out walking for 20 yards, then quickens the pace to a jog for 20 yards, and then to a full out run for 20 yards. Trial F: Student runs for 20 yards, then slows to a jog for 20 yards, and then walks for 20 yards.
Table for each trial should have position and time recorded for EVERY 10 YARDS. • For trials A-D (Time should be on the X-axis!!!): • Graph trials A-D on a position-time graph. • Calculate the slope for trials A thru D from the p-t graph. • Graph velocity vs time for trials A-D on a velocity-time graph. Again, time should be on the X-axis. • Calculate the slope for trials A-D from the v-t graph. • Graph acceleration vs time for trials A thru D on an acceleration-time graph.
For trials E-F(Time should be on the X-axis!!!): • Graph trials E-F on a position-time graph. • Calculate the slope of each line segment to get a picture of what the velocities were for each trial. • Graph the velocities on a velocity-time graph • If the velocities were to increase at a constant rate, what would the acceleration-time graph look like?
