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.
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.
The slope of a distance-time graph represents speed.
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.
