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?
distance divided by time squared
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]
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.

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 the dimensional formula of acceleration due to gravity?
An acceleration is a velocity divided by a time, so you have: acceleration = velocity / time acceleration = (distance / time) / time acceleration = distance / time2 The gravitational field can also be expressed as force / mass; this is equivalent to distance / time2.
What is acceleration time graph?
The change in the velocity divided by time in meters per second squared.
