Placed bells are at distances proportional to the time squared, 4, 9, 16, 25, 36, 49 units of measurement. That spacing yields a larger and larger gap between bells. • Yet, the bells ring a steady rhythm. This is due to acceleration, the change in velocity over time. • Galileo showed this with an inclined plane and bells. • We replicated Galileo's gravity bells here, with hot wheels car, track, and bells on our stairs. • Then we modeled the same thing with kids code in Scratch, where you can easily change the variables: https://scratch.mit.edu/projects/1079... • The even time between bells sounding is due to the distance being proportional to time squared, a parabolic relationship. • • We can call this parabolic gravity. A thrown object follows a parabolic curve, The object's vertical displacement is proportional to the square of the time in the air. This is a natural case of squaring in the relationship between time and distance due to the constant acceleration of gravity. • #stemeducation #unschool #diyscience
