Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

We are performing an experiment to calculate drag coefficient that involved dropping a beach ball off of an indoor balcony and recording the time it takes to hit the ground. Would the drag coefficient be positive or negative? My group and I are stuck wondering if acceleration due to gravity should be negative or positive when calculating for D in the following equation. And also we dont know if velocity in the equation should be negative since it is travelling in the negative y direction.
