For a projectile, velocity in the horizontal direction remains constant while velocity in the vertical direction changes.
Understand the Problem
The question is asking about the relationship between the horizontal and vertical components of velocity for a projectile, specifically what happens to the horizontal velocity while the vertical velocity changes.
Answer
remains constant; changes due to gravity
The final answer is: remains constant; changes due to gravity.
Answer for screen readers
The final answer is: remains constant; changes due to gravity.
More Information
In projectile motion, the horizontal velocity remains constant because there are no forces acting in the horizontal direction, while the vertical velocity changes due to the gravitational force pulling it downwards.
Tips
A common mistake is to assume that horizontal and vertical motions influence each other. In reality, they are independent.
