Suppose you throw some object near the surface of the earth. If the only significant force on the object is the constant downward gravitational force, we call this "projectile motion." Yes, that ...

I’ve started recreating many of my numerical model tutorials for introductory physics. In the beginning, I had students use spreadsheets to create models. Of course, spreadsheets aren’t very good for ...

This study presents a parametric investigation of soil-projectile interaction under low-velocity penetration with a focus on the joint effect of granular soil properties and projectile characteristics ...
