Question

A. In the athlete sprint scenario, apply distance-time graph to interpret a curved distance-time graph as changing speed while keeping distance versus displacement separate.
B. In the athlete sprint scenario, mix up distance versus displacement and ignore distance-time graph.
C. Use a general revision statement without applying Distance-time graphs to the situation.
D. Choose a different forces topic instead of explaining interpret a curved distance-time graph as changing speed.

Answer

The correct answer is: In the athlete sprint scenario, apply distance-time graph to interpret a curved distance-time graph as changing speed while keeping distance versus displacement separate.

Explanation

The correct option is In the athlete sprint scenario, apply distance-time graph to interpret a curved distance-time graph as changing speed while keeping distance versus displacement separate.. It is correct because the scenario says speed changes over a measured time interval, which must be interpreted through Distance-time graphs. This directly supports the learning objective to interpret a curved distance-time graph as changing speed. Use values 4, 13, and 22 only if the question asks for a calculation. The answer earns credit by naming the relevant force or motion quantity, using units when needed, and avoiding the boundary error distance versus displacement.

Common mistake

Curved Distance-Time Graphs

Students often misinterpret a curved distance-time graph as constant speed instead of changing speed.

To fix this, students should remember that a curve indicates that the speed is not constant and is changing over time. They can practice by analyzing different curves and describing how the speed changes.
