What is the initial velocity in a velocity-time graph?
The initial velocity of each object is the same as the final velocity is the same as every velocity in between. The velocity of each of these objects is constant during this ten second interval. In comparison, when the curve on a velocity-time graph is straight but not horizontal, the velocity is changing.
Why does a velocity-time graph not go through the origin?
the reason why a “v vs t” doesnt always pass through the origin is because you cant instantaneously reach a constant acceleration, a cart for example, will have to accelerate un-uniformely until it reaches a constant acceleration.
What is the relationship between initial velocity and time?
The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant….velocity-time.

What does a velocity-time graph show that changes over time?
A velocity-time graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.
How do you find initial velocity on a graph?
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates for these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
What does the slope of a velocity time graph indicate?
The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). The slope of a velocity-time graph reveals information about an object’s acceleration.
What is the relation between initial velocity final velocity acceleration and time?
Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth’s gravitational force as the acceleration rate of an object.
What does slope of velocity time graph represent?
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
