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).
Once to measure rate of displacement (speed)
and Second to measure the rate of chance of speed.
the unit of acceleration is unit length per squared unit time, usually m/s2.
The SI unit for acceleration is meters per second squared. This applies to ANY acceleration.
The unit of centripetal acceleration is meters per second squared (m/s^2). It represents the change in velocity per unit time in the direction towards the center of the circular motion.
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.
feet per second squared,
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.
the unit of acceleration is unit length per squared unit time, usually m/s2.
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)
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."
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
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.
The SI unit for acceleration is meters per second squared. This applies to ANY acceleration.
The SI unit for acceleration is the meter per second squared (m/s 2).
The SI unit is meters per second squared. More generally, you can measure it as any units of:length / time / time
