On a graph of speed versus time, where time is plotted along the horizontal (X) axis and speed along the vertical (Y) axis: -- constant speed (zero acceleration) produces a straight, horizontal line; -- constant acceleration produces a straight, sloped line; the slope of the line is equal to the acceleration; -- if the acceleration is positive, the line slopes up to the right (speed increases as time increases); -- if the acceleration is negative, the line slopes down to the right (speed decreases as time increases).

How Can you tell from a velocity-time graph that the velocity is constant?
velocity is nothing but speed of a body in the given direction. suppose if body is moving with constant velocity then VT graph will be parallel to the X -axis, if not then the VT graph is not parallel to the X-axis it means then object is moving with different velocity or it has its dierection or both velocity and aswell as direction.
How do you calculate distance with initial velocity and time?
v=d/t Algebra can be used to isolate for the t value: Multiply by t: vt=d Then, divide by v: t=d/v Now, simply plug in the given values for the variables, and solve.
Suppose that an object is traveling along a straight line Suppose that its velocity function is given by vt equals 4t2 -8t where t is in seconds Find the objects average acceleration along the time?
The average acceleration of the object over a time interval [a, b] is given by (v(b) - v(a))/(b - a). Given v(t) = 4t^2 - 8t, the average acceleration over the interval [a, b] is (4b^2 - 8b - (4a^2 - 8a))/(b - a).
Can we calculate distance between sun and earth by using formula s equals vt?
This method assumes a constant speed, and can be used if there is an object travelling from Sun to Earth, or from Earth to Sun (at constant speed, of course), and you know both the speed and the time it takes. It doesn't seem to be a very practical method in this case. Note that if you throw an object toward the Sun, it will go faster and faster, due to the Sun's gravitation, so you wouldn't have a constant speed. You can use the equivalent formula with integrals, of course.
