Question

acceleration due to gravity on earth is always
9.8 m
9.8 m/s²
9.8 s
9.8 m/s

Explanation:

Acceleration has the unit of \(m/s^{2}\). The acceleration due to gravity on Earth is a constant value, and its standard unit is \(m/s^{2}\). Among the options, \(9.8m\) is a unit of length, \(9.8s\) is a unit of time, \(9.8m/s\) is a unit of velocity. Only \(9.8m/s^{2}\) is the correct unit for acceleration.

Answer:

\(9.8m/s^{2}\)
