Question

the gravitational acceleration (little g) of an object near the surface of the earth is
o g = 9.8 m/s
o g = 9.8 m
o g = 9.8 m/s²
o g = 9.8 s

Explanation:

Step1: Recall acceleration unit

Acceleration is the rate of change of velocity with respect to time. Its SI - unit is $\frac{m}{s^{2}}$.

Step2: Identify correct option

Since gravitational acceleration is an acceleration, its unit should be $\frac{m}{s^{2}}$. Among the options, $g = 9.8\ m/s^{2}$ has the correct unit for acceleration.

Answer:

$g = 9.8\ m/s^{2}$
