Calculadora de Movimento Circular

The circular motion calculator solves rotational kinematics problems for uniform circular motion (UCM). It calculates tangential velocity (v) from angular velocity (ω) and radius (r), and centripetal acceleration (a_c) from angular velocity and radius. The formulas used are v = ω·r and a_c = ω²·r, which describe the relationship between linear and angular quantities in circular paths.

To use the calculator, enter two known values among angular velocity, radius, and tangential velocity to obtain the third, or enter angular velocity and radius to calculate centripetal acceleration. The tool is useful in contexts such as mechanical engineering, experimental physics, and projects involving rotation, like rollers, pulleys, and centrifuges. It provides instant results with adjustable precision.

Important precautions: ensure units are consistent (rad/s for ω, m for r, m/s for v). Uniform circular motion assumes constant angular velocity; if angular acceleration is present, other formulas are needed. Centripetal acceleration is always directed toward the center of the path, but the calculator provides only the magnitude. In real situations, consider friction and air resistance, which may alter the values.
