How is average velocity different from acceleration?
For a start, acceleration doesn't even have the same units as velocity: acceleration is a velocity divided by time, so while speed or velocity have units of [distance]/[time], acceleration has units of [distance]/[time squared]
Why you have second square in the unit of acceleration?
Square seconds, by itself, doesn't make much sense. On the other hand, please note that acceleration is not the same as speed or velocity, therefore you would expect the units to be different between the two. Speed or velocity is measured in meters / second; since acceleration is the change of rate of a velocity (in symbols: dv/dt), its units are velocity / time. Using SI units, that would be (meters / second) / second, and this is commonly written as meters / second2, which makes sense since the seconds appear twice in the denominator.
How is the speed of moving object measured?
Speed is measured by dividing your time into distance to come up with your velocity. speed is measured the same way as velocity. If you have a varying speed with acceleration and deceleration this would need to be factored in as well.
Is velocity the same as acceleration?
Both are vectors. But acceleration and velocity have different dimensions. Acceleration is defined as the rate of change of velocity.
What has a velocity and acceleration vector in the same direction?
Any falling object has acceleration and velocity vectors in the same direction.
What is deceleration measured in?
Deceleration means to decrease the velocity. The SI unit is the same as acceleration. In SI units, acceleration is measured in meters/second² (m·s-2).
How is average velocity different from acceleration?
For a start, acceleration doesn't even have the same units as velocity: acceleration is a velocity divided by time, so while speed or velocity have units of [distance]/[time], acceleration has units of [distance]/[time squared]
Is it possible for a body to have the same acceleration and velocity?
The velocity and acceleration can have the same numeric value, but the units will be different. ----------------------------------------------------------------------------------------- No it is not possible. Because so long there is acceleration then the velocity has to change either in magnitude or in direction or in both. So it is not at all possible for acceleration and velocity to be the same simultaneously.
Is acceleration measured in units of distance and time?
Acceleration as measured in the metric system base units is meters per second squared. The idea is that distance divided by time is speed. Speed divided by time is acceleration. (m/s/s = m/s^2)In Standard Units, acceleration is usually measured in feet per second squared or miles per hour squared.AnswerAcceleration 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 units are used to measure acceleration in free fall?
(any unit of distance) divided by (any unit of time)2 is a unit of acceleration.The acceleration of gravity is usually expressed in meters/second2 or feet/second2 .
Is velocity the same as acceleration?
Both are vectors. But acceleration and velocity have different dimensions. Acceleration is defined as the rate of change of velocity.
What is initial velocity measured in?
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.
Are speed and acceleration the same?
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
What has a velocity and acceleration vector in the same direction?
Any falling object has acceleration and velocity vectors in the same direction.
If two automobiles have the same acceleration do they have the same velocity?
No. V=v0 +at is the formula for velocity, the acceleration 'a' can be the same but the initial velocity v0 may be different. If v0 is the same for the two automobiles , the velocity would be the same.
