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...
متن کاملProjectile 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...

15 صفحه اولA Group Theoretical Formalization of Contact Motion
The work reported in this paper applies group theory to characterize local surface contact among solids, and makes such a formalization computationally tractable. This paper serves three purposes: (1) to report a new treatment of contacting surfaces as oriented sets and to verify the consistency of their corresponding symmetry groups in a group theoretical formalization framework; (2) to give a...
متن کاملProjectile 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...
