Answer:
A speed-versus-time graph displays the fan cart's motion phases, including constant speed, acceleration, and deceleration. The slope of the graph represents changes in speed over time, corresponding to the fan cart's motion characteristics. The correct multiple-choice option is all of these.
Step-by-step explanation:
The speed-versus-time graph for a fan cart experiment can provide various insights into the cart's motion. The graph describes how the speed of the fan cart changes over time and is indicative of different phases of the motion such as initial acceleration, constant speed, constant deceleration, or a combination thereof such as acceleration followed by deceleration.
If we see a straight horizontal line on the speed-versus-time graph, it would suggest the fan cart is moving at a constant speed. If the line slopes upwards, the cart is accelerating, while a downward slope would indicate deceleration. A graph of acceleration vs. time would provide additional details, showing zero acceleration during constant speed segments, and a positive or negative value during acceleration or deceleration phases, respectively.
By understanding these relationships, one can determine the motion characteristics of the cart at any given point during the experiment. This analysis is important in physics to understand concepts of motion, speed, and acceleration. The correct multiple-choice option is all of these.
