g = 9.8 m/s.

g = 9.8 m.

g = 9.8 m/s².

g = 9.8 s.

It accelerates at a constant rate until it hits the ground

It accelerates at a non-constant rate until it hits the ground

It accelerates at a constant rate until it reaches terminal velocity

It accelerates at a non-constant rate until it reaches terminal velocity

V_i ^{- initial velocity}

V_f ^{- final velocity}

d ^{- distance}

Falling objects accelerate at 9.8 m/s²

Falling object move at constant velocity

Falling objects accelerate at 100 m/s²

It depends on the mass: heavy objects accelerate, light objects do not

the velocity increases by about 10 m/s each second

the velocity decreases by about 10 m/s each second

the velocity remains constant

the acceleration increases by about 10 m/s each second.

the acceleration decreases randomly.

the acceleration remains constant.
