Projectile motion
Horizontal and vertical motions, each playing out on its own.
Horizontal projectile motion can be split into uniform motion in the horizontal direction and free fall in the vertical direction. The time to hit the ground depends only on the height and the gravitational acceleration.
Vertical displacement vs. time
Think about it
From the same height, if the initial speed is doubled, does the time to hit the ground change?
No. The time of flight t = √(2h/g) does not depend on the horizontal initial speed, but the horizontal range doubles.

Data log
Set the parameters and click “Record data”. Record several rows with different parameters to plot their relationship and fit a straight line; pause and record at different times to study how a reading changes with time.
