NCERT · Class 11 · Physics · Motion in a PlaneWhich of the following remains constant during the flight of an ideal projectile in air (neglecting air resistance)?
Step-by-Step Solution
In the absence of air resistance, the only force acting on a projectile is gravity, which acts vertically downwards. Consequently, the horizontal component of acceleration is zero, making the horizontal component of velocity constant throughout the flight.
