Lab 3.1 Projectile Data

Course: HPHYS
Unit: 3
Deconstructing Vertical Motion

A single data table generated from a simulation of a projectile launched at an angle. The dataset tracks the horizontal position (d_x) and vertical position (d_y) of a projectile at regular time intervals (t).

  1. Focus only on the 'Time' and 'Vertical_Position' columns. Describe what happens to the projectile's height during its flight. At what time does it reach its maximum height?
  2. Calculate the change in vertical position for the first second of flight (from t=0 to t=1) and the last second of flight. Are they the same? What does this suggest about the projectile's vertical speed?
  3. [SEP] If you were to create a plot of 'Vertical_Position' vs. 'Time', what shape would you expect the graph to have? How does this shape relate to the motion of an object dropped straight down? [BACKGROUND KNOWLEDGE: The motion of an object under constant acceleration, like gravity, produces a parabolic position-time graph.]
Deconstructing Horizontal Motion

A single data table generated from a simulation of a projectile launched at an angle. The dataset tracks the horizontal position (d_x) and vertical position (d_y) of a projectile at regular time intervals (t).

  1. Now, focus only on the 'Time' and 'Horizontal_Position' columns. Describe the relationship between how much time has passed and how far the projectile has traveled horizontally.
  2. Calculate the horizontal distance traveled during the first second of flight (from t=0 to t=1) and during any other one-second interval. What do you notice?
  3. [SEP] Calculate the ratio of 'Horizontal_Position' to 'Time' for at least three different data points. What does the consistency of this ratio tell you about the projectile's horizontal motion?
