its acceleration is constant
Free fall: brick A is dropped from the top of a building. Brick B is thrown straight down from the same building, and neither one experiences appreciable air resistance. Which statement about acceleration is correct?
The two bricks have exactly the same acceleration
Projectile motion: for general projectile motion with no air resistance, the horizontal component of a projectile’s acceleration
is always zero
Projectile motion: for general projectile motion with no air resistance, the vertical component of a projectile’s acceleration
remains a non-zero constant
