accelleration
No. The slope on a speed vs time graph tells the acceleration.
No. The vertical value of each point (the y-value) tells the 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.
No. The vertical coordinate tells the speed in this case. The slow is the derivate of the speed, i.e., the acceleration.
acceleration
The slope of a line on a distance-time graph represents the speed or velocity. The steeper the line is and the greater the slope of the line is, the faster the object is moving.
The slope of the graph line or curve.
You can't determine velocity from that graph, because the graph tells you nothing about the direction of the motion. But you can determine the speed. The speed at any moment is the slope of a line that's tangent to the graph at that moment.
-- If the position/time graph is a straight line, then the speed is constant, and the slope of the line is the average speed, as well as the instantaneous speed at any moment. -- If the position/time graph is not a straight line, then the average speed between two moments in time is the slope of a straight line drawn between those two points on the graph.
The graph is a straight line. Its slope is the speed.
If you graph distance vs. time, the slope of the line will be the average speed.
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.
