Question

complete the vpython code to move the object up three units.
ballposition = vector(0, 0, 0)
myball = sphere(= ballposition, color = color.green)
for n in range(10):
rate(1) # number of loops per second
myball.pos. □ = myball.pos. □ + 3

Explanation:

Step1: Understand VPython position vector

In VPython, the position vector has \(x\), \(y\), and \(z\) components. Moving up means changing the \(y\) - component.

Step2: Update the \(y\) - component

The code to update the \(y\) - component of the position vector is myBall.pos.y = myBall.pos.y + 3

Answer:

The first box should be filled with y and the second box should also be filled with y. So the completed code line is myBall.pos.y = myBall.pos.y + 3
