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. Air resistance does significantly alter trajectory motion, but due to the difficulty in calculation, it is ignored in introductory physics. That is, the flight time is the time required for the height to become 0 (the projectile reaches the ground). If v is the initial velocity, g acceleration due to gravity and H maximum height in meters, angle of the initial velocity from the horizontal plane (radians or degrees). It is calculated for y = 0, the vertical component of the position. The range of the projectile is dependent on the initial velocity of the object. The types of Projectile Motion Formula are: Horizontal Distance x Vx0t. The object moves along a curved route only. The projectile motion formula is also known as the trajectory formula. 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. The path taken by the projectile or the object is a trajectory. 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. 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. The equation of position of the projectile motion is given by:
