These equations are known as the kinematic equations. Of course, we do not always know the change in velocity and elapsed time, so we must sometimes use other equations to solve for acceleration. In its simplest form, the equation for acceleration is given as: a = Δv⁄ t Where a is the acceleration of the object, Δv is the change in velocity, and t is the amount of time the change in velocity takes. There are two solutions for the launch angle.Acceleration is defined as the rate of change of velocity for an object. If the launch velocity is known, the required angle of launch for a desired range can be calculated from the motion equations.įrom the range relationship, the angle of launch can be determined. Variation of the launch angle of a projectile will change the range. It can also be calculated if the maximum height and range are known, because the angle can be determined.įrom the range relationship, the launch velocity can be calculated. The launch velocity of a projectile can be calculated from the range if the angle of launch is known. To reproduce the scenario in the diagram, the input value of y should be negative. Note that the value y in the illustration is downward and it is presumed that upward is positive. Solving for the horizontal distance in terms of the height y is useful for calculating ranges in situations where the launch point is not at the same level as the landing point. The basic motion equations give the position components x and y in terms of the time. Where will it land?The basic motion equations give the position components x and y in terms of the time. 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.

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.
