Frequently Asked Questions (FAQ)
How do you find angular velocity with radius?
- To find the angular velocity use the equation: ω = (r × v) / |r|², where v is the velocity and r is the radius.
Is radial velocity the same as angular velocity?
- Angular velocity is the rate of change of angle with time. Radial velocity is the component of the velocity of a particle along the line of sight of the observer.
What is the difference between angular velocity and tangential velocity?
- The difference between angular velocity and tangential velocity is that while angular velocity is a vector measured in radians per second, Tangential velocity is a linear property measured in meters per second. For an object rotating about an axis, while the angular velocity for every point on the object is the same, the tangential velocity of any point changes in proportion to its distance from the axis of rotation.
What is the formula for radial velocity?
- The radial velocity formula is v = (Δλ×c)/λ, where c is the speed of light, Δλ is the change in wavelength, and λ is the rest wavelength.
