Velocity is defined by physicists as both speed and direction, that is to say, if you are moving at 30 feet per second in a northerly direction, that is a velocity. Acceleration means a change in velocity. Physicists consider speeding up, slowing down, or changing direction all to be forms of acceleration; in more everyday usage, acceleration us used to mean speeding up and deceleration means slowing down. So, if your speed increases from 30 feet per second to 40 feet per second, that is acceleration.

Velocity is displacement divided by time.
Acceleration is velocity divided by time.
However both graphs are related! If you graph the AREA under the slope of the acceleration graph vs. time, this will be a velocity graph. If you graph the SLOPE of the velocity graph vs. time, this will be an acceleration graph.
When you learn calculus (unless you already know it) you will learn how you can switch between the two.

What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
How can you calculate acceleration from a velocity-time graph?
simply put the acceleration is the slope of the speed vs time graphTheory Partthink of it this way. the unit for speed is meters per second or m/sthe unit for acceleration is meters per second per second or m/s2so essentially if speed is the change in position per change in time, acceleration is the change in speed per change in time.Practical Partnow for the actual answer. look at the slope of your speed vs time graph at any time. that slope is the acceleration at that time. If you find the slope between two points on your graph, that gives you the average acceleration over that interval of time.
Is acceleration always in the same direction as the unbalanced force?
No, acceleration is change in velocity. (And velocity is speed in a certain direction.) If an object slows down, then it is changing velocity and thus accelerating. (In this case, the acceleration is negative.) If an object changes direction, then it's velocity changes, so this is also acceleration. (This is centripetal acceleration.)
What interpretation can you derive regarding the motion from the graph of instantaneous speed vs time graph?
At least two things regarding the motion can be interpreted from the graph of speed versus time.The slope of the graph represents the acceleration of the thing being charted.And the net area under the graph represents the position of the thing being charted.Each of these graphed as they change with time, on the same time scale as the original graph or some other one if more convenient.
What settings describe a displacement versus time graph?
Constant velocityZero acceleration and/or Moving object
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.
Can the average speed ever equal the instantaneous speed?
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
What can be determined from a velocity time graph?
The simplest answer is the velocity of an object at a given time. It is also possible to determine the acceleration and displacement - but only in the same direction as the velocity. No information on motion in a transverse direction can be determined.
What does the slope of a line on a velocity vs time graph represent?
The slope of the line of a speed-versus-time graph will give you acceleration. Remember that acceleration may be positive or negative, and in some cases, acceleration may be positive when speed remains the same.1 If the speed-time curve is linear or piecewise linear2, acceleration is, as stated above, merely the slope of the line segment. If, however, the graph is a smooth curve, then changing acceleration is represented. In other words, the rate of change of velocity -- delta-V over delta-T -- is not a constant. In that case, the slope of the line segment tangent to the curve at any given point is the acceleration at that point. Note 1: There is a discussion comment on this point.Note 2: See the web link for an example of a graph that is piecewise linear.
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.
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.
What is acceleration speed and velocity?
Speed is (distance covered) divided by (time taken to cover the distance).Velocity is a speed and its direction.Acceleration is any change of velocity.
What happens to the velocity if acceleration is zero?
The velocity stays the same, it is constant
Are instantaneous velocity and acceleration the same?
no.
When the acceleration of an object is zero what is the velocity at the same time?
As long as acceleration is zero, the object's velocity is constant.
