What is represented by a curvy graph in terms of motion?

A curvy graph in the context of motion typically represents constantly accelerated motion. This is indicative of a situation where the velocity of an object is changing at a consistent rate over time. In such scenarios, the slope of the graph, which corresponds to velocity, is not constant but is instead increasing or decreasing, thus creating a curve.

For example, if you consider the position-time graph of an object moving with constant acceleration, the shape of the curve is parabolic, reflecting the mathematical relationship between distance and time when acceleration is involved. In contrast, a straight line in a graph represents constant velocity, where there is no change in speed or direction, indicating uniform motion without acceleration.

Constantly accelerated motion implies that there is a non-zero net force acting on the object, which causes it to change its velocity, resulting in the curvilinear path depicted on the graph. This is fundamental in understanding kinematic equations governing the motion of objects under constant acceleration.
