Question

the chart shows the movement of a ball after several seconds.
column a is on the x - axis, and column b is on the y - axis. which titles should replace a and b?
the table under the chart shows... has column a with values 0, 4, 8, 12, 16 and column b with values 0, 2.5, 6, 8, 10.5.
options:

• column a should be time, and column b should be position.
• column a should be position, and column b should be time.
• column a should be velocity, and column b should be speed.
• column a should be speed, and column b should be velocity.

Explanation:

In ball movement tracking, time is the independent variable (plotted on the x-axis, Column A), as it progresses steadily. Position is the dependent variable (plotted on the y-axis, Column B), as it changes based on elapsed time. The other options are invalid: position cannot be the steady independent variable, and speed/velocity are not distinct in this context nor match the data pattern.

Answer:

A. Column A should be "Time," and Column B should be "Position."
