Semilog/Log Log Plot

[engineertobe]

A student drops a ball from 9 different heights and measures the velocity of the ball when it hits the ground for each height. To display the resulting data as a scatter plot that looks like a straight line, should she use a semilog plot or a log-log plot? Explain.

"from 9 different heights" is vague. What is the range of acceptable heights for this?

Can you say for certainty that the ball's ground velocities are exponential?


Could they be quadratic instead?
