📚 Topic Summary
Projectile motion is the study of objects moving through the air under the influence of gravity. A key factor influencing the range (horizontal distance traveled) of a projectile is the launch angle. In this lab activity, we investigate how different launch angles affect the range of a projectile, assuming a constant initial velocity and neglecting air resistance. The optimal launch angle for maximum range, in ideal conditions, is 45 degrees.

✏️ Part B: Fill in the Blanks
Complete the following paragraph using the words: gravity, parabola, velocity, maximum, 45 degrees.
Projectile motion is influenced by __________, which causes the projectile to follow a curved path known as a __________. The initial __________ of the projectile and its launch angle determine its range. In the absence of air resistance, the __________ range is achieved at a launch angle of approximately __________.
🤔 Part C: Critical Thinking
Imagine you are launching a water balloon at a target. Explain why choosing the correct launch angle is important for hitting the target. What factors, other than the angle, might affect your accuracy in a real-world scenario?
