Question

*What does the slope of a speed-time graph indicate?



* What is represented by area under velocity-time graph of a body?
​

Answer 1

Explanation:

A sloping line on a speed-time graph represents an acceleration. The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down.

The steeper the slope of the line the greater the acceleration.

If the line slopes upward from left to right, this means the object is speeding up. Its acceleration will be positive.

If the line slopes downward from left to right on the graph, this means that the object is slowing down. Its acceleration will be negative.

The area under a speed-time graph represents the distance travelled.

This is a velocity time graph of an object moving in a straight line due North.

The displacement of this object is the area of the velocity time graph.
