Question

what is the most useful way to draw/explain movement in 1d?
□ hotwheels and stopwatches
□ graph
□ pie chart
□ map

Explanation:

A graph can effectively represent one - dimensional movement by plotting position, velocity, or acceleration over time. Hotwheels and stopwatches are tools for experimentation, not a way of representation. Pie charts are for showing proportions of a whole, not movement. Maps are for geographical or spatial representation in more than one dimension.

Answer:

B. Graph
