A velocity-time graph is a visual representation of the relationship between an object's velocity and time. It shows how an object's velocity changes over a certain period of time.
The slope of a velocity-time graph represents the object's acceleration. A steeper slope indicates a higher acceleration. The area under the curve represents the object's displacement.
A horizontal line on a velocity-time graph means that the object's velocity is constant, and there is no acceleration. This could indicate that the object is at rest or moving at a constant speed.
A positive slope on a velocity-time graph indicates that the object is accelerating in the positive direction. A negative slope means that the object is accelerating in the negative direction or decelerating.
The displacement can be determined by finding the area under the curve on a velocity-time graph. This can be done by dividing the graph into smaller, known shapes (e.g. rectangles or triangles) and calculating their individual areas.
