Alright, future engineers!
**Torque** is the rotational equivalent of force, causing objects to rotate. Ex: `T = r * F * sin(theta)`. Pro-Tip: Maximize it by applying force perpendicular to the lever arm (sin(90)=1)!

Hey future engineers! Torque is the rotational equivalent of force, causing angular acceleration. Formula: `Torque = rFsin(theta)`. Ex: Loosening a stubborn bolt. Pro-Tip: Always apply force perpendicular to the lever arm (r) for maximum turning power! #Physics #RotationalMotion #STEM #StudyNotes

Researchers develop new technology to measure rotational motion of cells

Mechanics plays a fundamental role in cell biology. Cells navigate these mechanical forces to explore their environments and sense the behavior of surrounding living cells. The physical characteristics of a cell's environment in turn impact cell functions. Therefore, understanding how cells interact with their environment provides crucial insights into cell biology and has wider implications in medicine, including disease diagnosis and cancer therapy.
