Difficulty: Easy
Correct Answer: Correct
Explanation:
Given data / statement
The item defines the range of a projectile as the horizontal distance from launch point to the point where it lands.
Concept
In ideal projectile motion (uniform gravity, no air resistance, level landing), the range is the horizontal displacement between the point of projection and the point of impact.
Clarification
Standard notation: If initial speed is u and projection angle is θ, then on level ground the range is R = (u^2 sin 2θ)/g, which is the horizontal distance between start and landing.
Common pitfall
Do not confuse range with the maximum height (vertical displacement) or the time of flight (duration in the air).
Final Answer
Correct
