The angle of the trajectory in a given point is the same as the angle that the velocity vector form with the horizontal at that point. Once the strong> flight time is obtained, simply substitute in the equation of position of the horizontal component. It is the maximum horizontal distance, from the starting point of the motion to the point in which the body hits the ground. That is, the flight time is the time required for the height to become 0 (the projectile reaches the ground). It also gives the completed details on steps to find the projectile motion time of flight and get the solved questions. It is calculated for y = 0, the vertical component of the position. Time of Flight Projectile Motion Calculator: This is an online physics calculator tool that is used to calculate the time of flight of a projectile in a fraction of seconds. From that time, and from the equations of position, we can calculate the distance to the origin in the both axes, the x-axis and y-axis. Starting from the equation of velocity in the y-axis, and making v y = 0, we get the time t that it takes the body in get to this height. This value is reached when the velocity in the y-axis, v y , is 0. On the other hand, frequently in exercises, you would be asked for some of the following values. Then, we plug vy and gravitational acceleration ( g) into the flight time ( t) equation. This gives us the velocity components for the x (horizontal) and y (vertical) directions. On the other hand, to know which trajectory the body follows, that is, its equation of trajectory, we can combine the above equations to eliminate t, getting:Īs expected, this is the equation of a parabola. First, we plug the initial velocity ( v0) and launch angle ( ) into the vx and vy equations. The equation of position of the projectile motion is given by:
