The height is not linear depending on time. Then the incorrect option is D.
<h3>What is a linear equation?</h3>
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
In linear motion, the height of the object is given as,
u = √(2gh)
From the first equation on motion, we have
v = u - gt
0 = √(2gh) - gt
2h = gt²
h = gt² / 2
Thus, the height is not linear depending on time.
Then the incorrect option is D.
