which physical identity has the unit ms-2
Answers
Given : ms⁻²
To find : physical identity has given unit
Solution:
ms⁻²
= m/s²
m - unit of length ( displacement / distance / length )
s = unit of time
Rate of change of distance / displacement is speed / velocity
m / s = velocity or Speed
Rate of change of velocity is acceleration
(m/s)/s = acceleration
=> m/s² = acceleration
=> ms⁻² = acceleration
acceleration has unit m/s²

Answer:
acceleration = ms-2
Explanation:
Looking at ms-2, this can be broken down into two basic dimensions.
One is distance whose unit is m
While the other dimension is time whose unit is s
Taking the rate of change of distance to time, we get velocity whose unit is;
V = distance / time
Velocity = m/s
Now if we take the rate of change of velocity we will get acceleration
a = v / t
acceleration = (m/s) / s
acceleration = ms-2
