Activity 1: Graph and interpret motion data of a moving object.

Activity 1 -. Table 1 Time (x axis) (seconds) Position (y axis) (meters) 0 0 5 20 10 40 15 50 20 55 30 60 35 70 40 70 45 70 50 55.

Question 1: What is the average speed of the train during the time interval from 0 s to 10 s?

The average speed from 0 s to 10 s is the total distance traveled divided by the time interval. That's (40 m - 0 m) / (10 s - 0 s) = 40 m / 10 s = 4 m/s.

Question 2: Using the equation v= (s2-s1)/(t2-t1), calculate the average speed of the train as it moves from position x = 50m to position x = 60m.

v = (s2-s1)/(t2-t1) = (60m-50m)/(30s-15s) = 10m/15s = 0.67m/s.

Question 3: What does the slope …show more content…
It tells me that the relationship between distance and displacement for an object traveling at a constant acceleration is dependent on each other and is exponential.

Activity 4: Predict the time for a steel sphere to roll down an incline.

Steel Sphere Acrylic Sphere A Length of Track (cm) (s) (Step 1, use 80 cm) 80 cm 80 cm B Angle of Elevation () in Degrees 0 (Step 1) 5 degrees 5 degrees C Calculated Time from s=0 to s=80 (formula from step 2) 3.03 seconds 3.03 seconds D Measured Time from s=0 to s=80 (step 3 with stopwatch) 3.18 seconds 3.46 seconds E % Difference (step 4) 4.8% 13.25% 13.25% 13.25% 13.

Question for Activity 4: What effect does the type of the sphere have on the time the object travels the measured distance, explain? The type of sphere (like steel or acrylic) can change how fast it rolls down a track because different materials can be heavier or stickier. A heavier sphere might roll down faster if it doesn't stick much to the track, and a lighter or stickier sphere might roll slower. So, the kind of material the sphere is made of can make it take more or less time to roll the same
