They are cratered because of meteoroids, neither of them have an atmosphere to disintegrate the meteors, and neither of them have water to erode the craters.
When an object is free-falling, no other force is acting upon it but the gravitational force. Because of this, the equations of motion are simplified. We can determine first the initial velocity:
v = √2gy = √2(9.81)(4.9) = 9.805 m/s
Then, we use this to the equation below: y = vt + 1/2*at² y = (9.805)(0.5) + 1/2(9.81)(0.5)² y = 6.13 m
Linear motion (also called rectilinear motion) is a motion along a straight line, and can therefore be described mathematically using only one spatial dimension.
