If the slope is 'uphill' then the car is going faster
The graph is a straight line. Its slope is the speed.
If you are plotting distance versus time it is a straight line with slope 300000
Yes. Speed is the rate at which distance changes over time. In calculus terms v = dx/dt, or the slope of the distance vs. time graph. If the slope of the distance vs. time graph is a straight line, the speed is constant.
the slope would be speed.
The slope of a distance-time graph represents speed.
It tells you that the speed of the object is not changing. The speed is represented by the slope in a distance vs. time graph, if slope doesn't change, speed doesn't.
If it is distance from a point versus time, with distance on the vertical axis and time on the horizontal axis, it would show a steep vertical climb on the graph. The steeper vertical change, the faster, but never completely vertical. Large "rise" (distance) over short "run" (time). With 0 acceleration, the graph is a straight line.
The constant acceleration
No. The slope of the distance-time graph is the change in distance per unit of time - otherwise known as speed. Acceleration is the slope of the speed time graph.
Slope of time Vs distance graph gives the inverse of velocity.
acceleration
At constant speed, the distance/time graph is a straight line, whose slope is equal to the speed.
