For undergraduate introductory physics courses student must be taught about projectile motion. Basketball shooting can be used as a case study for learning projectile motion from real-life situation. In this research, we discuss the relationship between optimal angle, minimum initial velocity and the ...
For example, if you are analyzing the motion of a ball thrown downwards from the top of a cliff, it may make sense to define the positive direction downwards since the motion of the ball is solely in the downwards direction. If this is the case, g takes a positive value. Example 2. ...

While the projectile is exiting, the muzzle can vibrate in a transverse motion thus imparting side thrust to the projectile. It is therefore necessary, in some but not all cases, to provide anchoring of the muzzle to prevent any lateral motion or to increase the mass so as to minimize the...
