WebFeb 20, 2024 · Notice that when the rock is at its highest point (at 1.5 s), its velocity is zero, but its acceleration is still − 9.80m / s2. Its acceleration is − 9.80m / s2 for the whole trip—while it is moving up and while it is moving down. Note that the values for y are the positions (or displacements) of the rock, not the total distances traveled. http://pressbooks-dev.oer.hawaii.edu/collegephysics/chapter/2-7-falling-objects/

Stage 1: When you throw a ball up you apply a force to the ball in the upward direction as long as it is in contact with your hand. This force does some amount of work on the ball. This work done is manifest as the sum of kinetic energy and potential energy of the ball. flexy creatorsWebDec 21, 2024 · Let's have a look at the final time of flight equation again: the higher the value of sine is, the longer the time in the air. The maximum value of sine occurs when the angle = 90°. So if you throw an object upwards, it will keep moving for the longest time. Additionally, if the velocity is equal to 0, then it's the case of a free fall. chelt clc
