6/26/2023 0 Comments Projectile motion equationsThis equation can also be rearranged to solve for time - use the quadratic formula to get the final answer. To find the maximum height substitute V y = 0 at any other point use t to find the height of the projectile. The Range (R) is the maximum horizontal distance: The horizontal distance is calculated by: (use in non-accelerated motion conditions only) The horizontal velocity of a projectile is always constant Projectile Motion equations and Linear Motion Equations These are given so that you can identify the correct conditions to use each equation in solving problems. See illustration below.Įquations of motion relating to projectiles a y = -9.8 m/s 2).Īt the top of its flight (at t 1/2), the slope of the tangent to this parabola is zero, therefore the vertical velocity V y at that point is zero.Ī projectile launched at angle and an object dropped at the same time from the same height, will reach the ground at the same time. The vertical velocity V y, is affected by gravity - it is positive but decreasing for the first part of the trajectory and negative but increasing for the second part of the trajectory. The horizontal velocity V x, is always constant - not affected by gravity (i.e. Important Physics principles of projectiles:
