如何计算Centripetal Force
learn.whatIsHeading
Centripetal force is the net force directing an object toward the center of circular motion. Without it, objects move in straight lines; it's essential for understanding circular motion.
公式
F = m × v² / r = m × ω² × r
分步指南
- 1Enter mass, velocity, and radius of circular path
- 2Calculate using either velocity or angular velocity form
- 3Result is the required centripetal force
例题解析
输入
m = 2 kg, v = 5 m/s, r = 1 m
结果
F = 50 N
2 × 25 / 1 = 50
常见错误注意事项
- ✕Confusing centripetal with centrifugal (fictitious)
- ✕Wrong radius measurement
