Analytical velocity hodograph of projectile motion under polynomial drag

Projectile Motion

The steel ball will be launched horizontally by being released at a certain height on the ramp. It will then fall to the floor and make a mark on the landing paper. The horizontal distance from take-off to landing, x, is proportional to the initial horizontal velocity, v0, of the ball. The distance, x, can be measured with the meter stick. By using the SALT®, photogate and computer, the time ca...

Projectile Motion

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. Howeve...

Analytical Approach to Ballistic Dispersion of Projectile Weapons Based on Variant Launch Velocity

Projectile Motion in Real Life

Projectile motion is a fundamental concept in basic physics courses. The often used simplified calculations, where air resistance is neglected, are obviously not relevant for many real life events. Using a video camera and computer software, students can investigate the influence of air resistance on for instance the trajectory of a football. The video sequences are digitised and the xand y-pos...

Drag Coefficient Measurements for Typical Bomb and Projectile Fragments

The FRAGHAZ computer program has been developed to predict the hazardous regions due to fragments produced by an accidential explosion of stored ammunition. Determination of these hazardous regions is based on computer simulations of fragment trajectories. Currently, the fragment drag coefficients used in the program are extrapolations of subsonic drag coefficients out to transonic and superson...
