![]() There is no slider to adjust the acceleration of gravity, which remains constant on the Earth at -32 or -9.8 in the vertical direction. You can also adjust the initial vertical position and velocity to see what effect this has on the distance the projectile goes before striking the ground, as well as observing how high it goes. The formula has four variables: final height (Hf), initial height (H0), initial. ![]() You will see that no matter what you do to these 2D sliders, the projectile will still hit the ground at the same time and that changing them will not change the height of the projectile at any given time in its motion. The projectile formula is an equation that is used to calculated the height of a projectile at any given time. ![]() Using the horizontal direction controls, you can change the initial position and velocity in both horizontal axes. The equations of rectilinear motion that you learnt about in Grade 10 can be used for vertical projectile motion, with acceleration from gravity: ag. When a particle is thrown obliquely near the earths surface, it moves along a curved path under constant acceleration directed. Second, try rotating the path until you have an "edge-on" angle so that you can see that vertically, the projectile is accelerating and the rates going up and going down are identical. You should be able to see that the spacing of the track is constant, regardless of the simulation's settings, implying a constant horizontal velocity. First, try running the time forward with tracking turned on, pausing the simulation, and rotating the projectile's path to an overhead view. The 3D animation of the projectile can be rotated and zoomed in or out in 3D. You also have the option to either track the projectile's motion or display the 3D vector of the projectile's velocity. The most important control is the time slider bar, which allows you to view the projectile at any moment in time. In this simulation of projectile motion, you can adjust a number of controls.
