چکیده
Introduction: A projectile is a body in free fall that is subject only to the forces of gravity (9.81ms⎯2) and air resistance. An object must be dropped from a height, thrown vertically upwards or thrown at an angle to be considered a projectile. The path followed by a projectile is known as a trajectory. If gravity were not present, a projectile would travel in a constant straight line. However, the presence of gravity forces projectiles to travel in a parabolic trajectory, thus gravity accelerates objects downwards.

متن کاملModified Linear Theory for Spinning or Non-Spinning Projectiles
Static and dynamic stability are the most important phenomena for stable flight atmospheric motion of spin and fin stabilized projectiles. If the aerodynamic forces and moments and the initial conditions are accurately known, an essentially exact simulation of the projectile’s synthesized pitching and yawing motion can be readily obtained by numerical methods. A modified trajectory linear theor...
متن کاملOn the Design of Embodiment-based Gamification Activities for Learning Fundamental Projectile Motion
Based on theories of embodied cognition, this study applied technologies of natural user interface to design gamification activities for learning fundamental projectile motion. The embodiment-based design facilitates elementary learners to learn the abstract concept of fundamental projectile motion through their body-moving experience. When the learners perform gamification activities with thei...
