Mar 12, 2024 · It is reasonable to take the initial position \(y_{0}\) to be zero. This problem involves one-dimensional motion in the vertical direction. We use plus and minus signs to indicate direction, with up being positive and down negative.

The most remarkable and unexpected fact about falling objects is that, if air resistance and friction are negligible, then in a given location all objects fall toward the center of Earth with the same constant acceleration, independent of their mass.

where Δ Δ x is displacement, x f is the final position, and x 0 is the initial position. We use the uppercase Greek letter delta (Δ Δ) to mean “change in” whatever quantity follows it; thus, Δ Δ x means change in position (final position less initial position).

Jun 15, 2023 · In one dimension, the displacement of an object over a given time interval is a quantity that we denote as \(\Delta x\), and equals the difference between the object’s initial and final positions (in one dimension, we will often call the “position coordinate” simply the “position,” for short): \[ \Delta x=x_{f}-x_{i} \label{eq:1} \]
