9/29/09 yes,for example, a car goes past you at 80mph for 10s. What is the acceleration?
distance 80
a= time(2) a= 10 =8 acceleration=8mph

What does speed equals divided by time?
Speed is measured in units of (Distance) over (Time). So Speed divided by Time would be equivalent to (Distance) over (Time squared), which is the unit of measurement for Acceleration.
Why the second is squared in acceleration?
it is very simple........... velocity or speed = distance / time. acceleration = velocity / time but, we know that velocity = distance / time so just substitute the equation of velocity in acceleration...... so, finally we get , acceleration = distance/time*time so it is time squared.
How do you find time when given distance and acceleration?
Distance = (1/2 of acceleration) x (time squared)You can change this around to solve it for acceleration or time.(Time squared) = (distance)/(half of acceleration)Time = the square root of [ (2 x distance)/(acceleration) ]Be careful . . .This is only true if the distance and the speed are both zero when the time begins.
What is the homogeneity of v2 equals u2 plus 2as?
Each term in the equation has dimensions of velocity-squared (remember "a" here is acceleration which is velocity divided by time, so "as" is velocity x distance / time = velocity squared).
What is a distance vs time graph?
A distance vs time squared graph shows shows the relationship between distance and time during an acceleration. An example of an acceleration value would be 3.4 m/s^2. The time is always squared in acceleration therefore the graph can show the rate of which an object is moving
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.

Speed is measured in units of (Distance) over (Time). So Speed divided by Time would be equivalent to (Distance) over (Time squared), which is the unit of measurement for Acceleration.

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.
How do you get the acceleration of an object?
Acceleration= Distance divided by time

Where is acceleration represented on a distance verses time squared graph?
In general, nowhere, because acceleration is the second derivative of distance with respect to time. However, in the special case of a constant acceleration, the acceleration will be twice the slope of the line, since distance = 0.5 * time squared.
What do the graphs of distance vs time and distance vs time squared suggests?
distance vs time suggests velocity while distance vs time squared suggests acceleration

What is acceleration time graph?
The change in the velocity divided by time in meters per second squared.
What do the graphs of distance vs. time and distance vs. time square suggest?
The graph of distance vs. time suggests constant velocity if it is a straight line, while a curve on the graph implies changing velocity. The graph of distance vs. time squared suggests acceleration, as a linear relationship implies constant acceleration.
