Question

Assuming the downward direction to be positive, the acceleration of gravity is about 10 m/s

. This means that
A) the distance of a falling body increases by 10 m every second.
B) the time of a falling body is reduced by one second every 10 m.
C) the velocity of a falling body increases by 10 m/s
every second.
D) the velocity of a falling body increases by 1 m/s
every 10 seconds.

Answer 1

It means that the speed of a falling body
increases by about 10 m/s every second.

approximately (C)
