Projectile Velocity and Crater Formation in Water
International Scholastic Journal of Science, 2010 The relationship between the velocity of impact and maximum crater diameter was found for two steel balls dropped into water using 300 fps video. The maximum diameter of the crater was found to be proportional to the impact velocity and independent of ...

The influence of the drag force on the safety domain
Revista Brasileira de Ensino de FísicaIn this work we compute the safety domain related to projectiles fired close to the Earth's surface, taking into account a linear (laminar regime) and a quadratic drag force (turbulent regime).

Exploration of Wave Development during Yarn Transverse Impact
Fibers, 2017 Single yarns have been impacted in a transverse fashion so as to probe the characteristics of resulting wave development. Longitudinal wave speeds were tracked in efforts to directly measure the yarn tensile stiffness, resulting in a slight increase in ...

Experimental evidence for non-proportional growth of large craters [PDF]
Evidence from laboratory impact experiments is indicating that increasing crater aspect ratios (diameter:depth) can result from increasing both velocity and projectile size without invoking unusual impactor conditions.

1,2‐Diazetidines − Structure, Synthesis, and Functionalization
European Journal of Organic Chemistry, EarlyView.1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

The projectile inside the loop
Physics Education, 2006 In this paper we describe an alternative use of the loop-the-loop apparatus, which can be used to study an interesting case of projectile motion. We also present an effective way to perform and analyze these experiments, by using video capture software together with a digital video camera.
