Exp. 3: Projectile Range Versus Angle
Procedure
•
Shooting off a level surface:
•
Shooting off a table:
•
NOTE: The curves show the calculated ranges in each case. The data points are the actual measured ranges.
Questions
1.
On a level surface, the maximum range is at 45°. For a non-level surface, the angle of maximum range
depends on the initial height of the projectile. For the experimental setup, with an initial height of 1.15 m, the
maximum range is at 40° (versus the theoretical value of 39°).
2.
The angle of maximum range decreases with table height.
3.
The maximum distance increases with table height.
Exp. 4: Projectile Path
Analysis
1.
Alternately, measure your distances from the ground up.
