A projectile's horizontal velocity remains constant (ignoring air resistance) because
A.no horizontal force acts on it
B.gravity acts horizontally too
C.air resistance balances gravity
D.its vertical velocity is constant
Explanation
Core Concept
With no horizontal force, there is no horizontal acceleration, so horizontal velocity is constant.
Correct Answer
Ano horizontal force acts on it
