Time square by itself doesn't seem to make much sense, right?
You must consider that acceleration is NOT the same thing as velocity. Velocity (and speed) is expressed (for example) in meter/second. An acceleration is a change of velocity per time unit, so logically the units are (meters/second) / second. This is the same as meters/second2, and that is the way it is usually written.
Answer
Acceleration is the rate of change of velocity. In other words, it is velocity divided by time. As velocity (in SI) is expressed in metres per second, acceleration must be measured in 'metres per second per second'. In fact, this is the correct way of saying the unit of measurement for acceleration, NOT 'metre per second squared'. The symbol for metres per second per second is 'm/s/s' which, of course, is exactly the same as m/s2 (where 2 is a superscript).
What else can I help you with?
How does the unit of time enter twice in the unit of acceleration?
Acceleration is the rate of change of velocity over time. Since velocity is distance over time, acceleration becomes distance over time squared. This is why time enters twice in the unit of acceleration as distance per time squared.
What unit do you use to express free-fall acceleration?
the unit of acceleration is unit length per squared unit time, usually m/s2.
Why seconds are s2 (squared) in the acceleration formula?
Seconds are not squared in the acceleration formula. The units for acceleration are meters per second squared (m/s^2), where the time unit (seconds) is squared to represent the change in velocity over time.
What is the SI unit of negative acceleration?
The SI unit for acceleration is meters per second squared. This applies to ANY acceleration.
What is acceleration messured in?
Acceleration is typically measured in meters per second squared (m/s^2). This unit represents the change in velocity per unit time.

Measurements of acceleration are given in units of what?
Acceleration is the rate of change of the function of velocity per unit time. This means that the unit of acceleration is distance per unit time squared.
What unit do you use to express free-fall acceleration?
the unit of acceleration is unit length per squared unit time, usually m/s2.
Why seconds are s2 (squared) in the acceleration formula?
Seconds are not squared in the acceleration formula. The units for acceleration are meters per second squared (m/s^2), where the time unit (seconds) is squared to represent the change in velocity over time.

The SI unit for acceleration is meters per second squared. This applies to ANY acceleration.
What is acceleration messured in?
Acceleration is typically measured in meters per second squared (m/s^2). This unit represents the change in velocity per unit time.
What is acceleration measured in?
Acceleration is measured in (distance) per (unit of time) squared; for example, feet/second squared in the SI (metric) system the official unit is metres/second/second or metres/(second squared)
What is the standard SI unit for measuring acceleration?
The unit is meters per second squared (m/s2)Meters per second squared, or m/(s2). This should not be interpreted as "the square of a second" but instead as "meters per second, per second."
What are the units of acceleration?
Acceleration is a change in velocity per unit of time. Velocity is distance (d) per unit of time (t). That makes acceleration distance per unit of time squared, or something like this:We have distance/time2, or d/t2Distance is commonly measured in meters, and time in seconds. This makes acceleration appear in meters per second per second, or meters per second squared, or m/sec2.m/s2meters per second squared
Why does the (second)2 occurs in the unit of acceleration?
The unit of acceleration is meters per second squared (m/s^2) because it represents the rate of change of velocity over time. The squared term indicates that the velocity is changing with respect to time, thus indicating the acceleration over a given time interval.
What is the unit that g is measured in?
The acceleration of gravity, g, is measured in units of acceleration, which is to say units of distance per time squared. For example, meters per second squared.
What is the formula for acceleration and what would be an example of an acceleration units?
The basic formula for acceleration is the one that defines acceleration, as the rate of change of speed: a = dv/dt. For the case of constant acceleration, this is simply (change of velocity) / time. The unit is any unit of speed by a unit of time; in the SI that would be (meters / second) / second, usually written as meters / second squared.
