1. What is the Coriolis Force?

The Coriolis force is an inertial or fictitious force that acts on objects moving within a frame of reference that rotates with respect to an inertial frame. It is responsible for the deflection of moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

2. How Does the Calculator Work?

The calculator uses the Coriolis force equation:

Where:

• \( F_c \) — Coriolis force (N)
• \( m \) — Mass of the object (kg)
• \( \omega \) — Angular velocity vector (rad/s)
• \( v \) — Linear velocity vector (m/s)
• \( \times \) — Cross product operator

Explanation: The Coriolis force is proportional to the mass of the object and the cross product of the angular velocity and linear velocity vectors. The negative sign indicates the direction is opposite to the rotation.

3. Importance of Coriolis Force Calculation

Details: Understanding and calculating the Coriolis force is crucial in meteorology, oceanography, ballistics, and engineering. It affects weather patterns, ocean currents, and the trajectory of long-range projectiles.

4. Using the Calculator

Tips: Enter mass in kilograms, angular velocity in radians per second, linear velocity in meters per second, and the angle between the angular velocity and linear velocity vectors in degrees. All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: Is the Coriolis force a real force?
A: The Coriolis force is an inertial or fictitious force that appears in rotating reference frames. While not a fundamental force like gravity, its effects are very real and measurable.

Q2: Why does the Coriolis force affect large-scale phenomena?
A: The Coriolis force becomes significant when objects travel large distances over considerable time periods, allowing the Earth's rotation to have a noticeable effect on their trajectories.

Q3: Does the Coriolis force affect water draining in sinks?
A: For small-scale phenomena like sink drainage, the Coriolis effect is negligible compared to other factors like the shape of the basin and initial water motion.

Q4: How does latitude affect the Coriolis force?
A: The Coriolis force is maximum at the poles and zero at the equator, as it depends on the component of the Earth's rotation perpendicular to the surface.

Q5: What is the direction of the Coriolis force?
A: In the Northern Hemisphere, it deflects moving objects to the right of their direction of motion. In the Southern Hemisphere, it deflects objects to the left.
