Centripetal Force Formula:
From: | To: |
Definition: This calculator computes the centripetal force required to keep an object moving in a circular path based on its mass, velocity, and radius of curvature.
Purpose: It helps engineers, physicists, and students analyze circular motion scenarios in mechanics and design problems.
The calculator uses the centripetal force formula:
Where:
Explanation: The formula calculates the inward force needed to maintain circular motion, accounting for the object's mass, speed, and path curvature.
Details: Proper force estimation is crucial for designing safe curves in roads, roller coasters, and rotating machinery, ensuring stability in circular motion systems.
Tips: Enter the mass in kilograms, velocity in meters per second, and radius in meters. All values must be > 0.
Q1: Why is gravitational acceleration (g) included?
A: The formula accounts for the weight component in systems where gravity affects the circular motion (like banked curves).
Q2: What if my object is in horizontal circular motion?
A: For purely horizontal motion, use the standard centripetal force formula \( F = m \times v^2 / r \) without the g factor.
Q3: How does radius affect the force?
A: Force is inversely proportional to radius - tighter curves (smaller r) require significantly more force at the same speed.
Q4: What units should I use?
A: Use kilograms for mass, meters per second for velocity, and meters for radius to get force in Newtons.
Q5: Can this calculate centrifugal force?
A: Centrifugal force is a fictitious force that appears in rotating frames; this calculator gives the real centripetal force needed.
