The basic motion equations can be solved simultaneously to express y in terms of x. The launch at 45 degrees gives the maximum range.įor launch velocity v 0 = m/s, launch angle θ = degrees: Note that the 60 and 30 degree trajectories have the same range, as do any pair of launches at complementary angles. The diagram shows trajectories with the same launch speed but different launch angles. The initial vector components of the velocity are used in the equations. The horizontal and vertical motions may be separated and described by the general motion equations for constant acceleration. General Ballistic Trajectory The motion of an object under the influence of gravity is determined completely by the acceleration of gravity, its launch speed, and launch angle provided air friction is negligible. The values below are output values those boxes will not accept input for calculation.The velocity will beĪll the parameters of a horizontal launch can be calculated with the motion equations, assuming a downward acceleration of gravity of 9.8 m/s 2.Ĭalculation is initiated by clicking on the formula in the illustration for the quantity you wish to calculate. You may enter values for launch velocity and time in the boxes below and click outside the box to perform the calculation.For launch speed v 0y = m/s= ft/s Given the constant acceleration of gravity g, the position and speed at any time can be calculated from the motion equations: Vertical motion under the influence of gravity can be described by the basic motion equations. But the calculation assumes that the gravity acceleration is the surface value g = 9.8 m/s 2, so if the height is great enough for gravity to have changed significantly the results will be incorrect. Note that you can enter a distance (height) and click outside the box to calculate the freefall time and impact velocity in the absence of air friction. The distance from the starting point will beĮnter data in any box and click outside the box. Since all the quantities are directed downward, that direction is chosen as the positive direction in this case. Its position and speed can be predicted for any time after that. Illustrated here is the situation where an object is released from rest. Position and speed at any time can be calculated from the motion equations.

In the absence of frictional drag, an object near the surface of the earth will fall with the constant acceleration of gravity g.

Wait until it finishes loading for full functionality. 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.Trajectories Note: This is a large HTML document. 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. 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. Using the horizontal direction controls, you can change the initial position and velocity in both horizontal axes. 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.
