objects that don't receive any othe force have acceleration a=10m/s, which means their velocity changes. the speed of an object is given by the formula u=V+a*t when the object is falling, and u=V-a*t when the obect is ascending., where u its current speed, V it's starting speed and t the time, and positive direction is down.
through the use of integrals it is proven that its position is x=V*t+(-)a*t/2. this is a parabola graph, so no it is not a straight line.

Which distance time graph most closley represents an object moving with a uniform motion?
A straight diagonal line on a distance-time graph represents an object moving with uniform motion. This line shows a constant speed where the distance covered increases at a steady rate over time.
What does a straight line slanting up from left to right on a distance versus time graph show?
It represents that the object is remaining at a fixed distance. Typically that means it is not moving.
What does an upward sloping diagonal line mean in position vs time graph?
It means that either the distance is measured from the starting-line and the object is moving forward, or else the distance is measured from the finish-line and the object is moving backwards, because the distance is growing as time goes on. If the upward sloping diagonal line is straight, it means the speed is constant. (not velocity)
Does a horizontal line on a distance-time graph means the object is moving at a constant speed?
Yes, a horizontal line on a distance-time graph represents an object moving at a constant speed. The slope of the line on a distance-time graph represents the speed of the object, and if the line is horizontal, it means the object is moving at a constant speed as there is no change in distance over time.
Can a position time graph have negative slope?
yes, if the speed is negative, that is, moving backward
