### Ekman Number

Wolfram Research

The Ekman number is a dimensionless number used in fluid dynamics to describe the ratio of viscous forces to Coriolis forces.

### Equation of Circular Motion under Constant Acceleration

Wolfram Research

The equation of circular motion describes an object moving under constant angular acceleration in a circular as a function of time.

### Accelerating Frequency

Wolfram Research

Fluid dynamic accelerating frequency

### Angular Velocity under Constant Angular Acceleration

Wolfram Research

The angular velocity of a body is the rate of change of its angular displacement with respect to time.

### Angular Velocity by Initial and Final Values

Wolfram Research

The angular velocity of a rotating body is defined as the rate of change of angular displacement.

### Angular Momentum of a Rigid Body

Wolfram Research

Angular momentum is the rotational analog of linear momentum. For a rigid body, it equals the cross-product of the particle's position vector (relative to some origin) and its momentum vector.

### Average Angular Velocity by Displacement

Wolfram Research

The angular velocity of a rotating body is defined as the rate of change of angular displacement.

### Centripetal Acceleration Using Angular Velocity

Wolfram Research

Centripetal acceleration is the rate of change of velocity of an object with respect to time as it moves in a circular path.

### Centripetal Force Using Angular Velocity

Wolfram Research

A centripetal force is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and toward the fixed point of the instantaneous center of curvature of the path.

### Coriolis Effect

Wolfram Research

The Coriolis force is an inertial force that acts on objects that are in motion relative to a rotating reference frame. In a reference frame with clockwise rotation, the force acts to the left of the motion of the obj...

### Equation of Motion Using Angular Displacement

Wolfram Research

Equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.

### Equation of Motion Using Final and Initial Angle

Wolfram Research

Equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.

### Power Exerted on a Rotating Object

Wolfram Research

Torque is a rotational force. Torque acting through a rotational distance over time creates power.

### Rotational Kinetic Energy

Wolfram Research

Rotational kinetic energy, or angular kinetic energy, is kinetic energy due to the rotation of an object and is part of its total kinetic energy.
