WebSep 10, 2024 · Solutions. We know that slope of distance-time graph represent the speed. In distance-time graph C, the speed of the object is constant for some time as the slope of distance-time curve is constant for some time. After some point of time, its slope increases. This means that the speed of object changes and object accelerates. Webmotion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity). The most general kind of motion … WebSpeed is a measure of how fast an object is moving. Calculate speed using the speed equation - speed = distance divided by time.
