To do this, we separate projectile motion into the two components of its motion, one along the horizontal axis and the other along the vertical. To calculate projectile motion without an angle, we have to know the equations of motion, which are. Since vertical and horizontal motions are independent, we can analyze them separately, along perpendicular axes. Calculating projectile motion without an angle. Keep in mind that if the cannon launched the ball with any vertical component to the velocity, the vertical displacements would not line up perfectly. #Projectile equations freeYou can see that the cannonball in free fall falls at the same rate as the cannonball in projectile motion. Include: horizontal and vertical components of motion of the. Figure 5.27 compares a cannonball in free fall (in blue) to a cannonball launched horizontally in projectile motion (in red). Solve simple free-fall problems using the special equations for constant acceleration. The most important concept in projectile motion is that horizontal and vertical motions are independent, meaning that they don’t influence one another. Ask students to guess what the motion of a projectile might depend on? Is the initial velocity important? Is the angle important? How will these things affect its height and the distance it covers? Introduce the concept of air resistance. If v is the initial velocity, g acceleration due to gravity and H maximum height in metres, angle of the initial velocity from the horizontal plane (radians or degrees). Review addition of vectors graphically and analytically. The range of the projectile depends on the object’s initial velocity.
