What does the radial velocity method measure?
What does the radial velocity method measure? The radial velocity technique is able to detect planets around low-mass stars, such as M-type (red dwarf) stars. This allows astronomers to determine the inclination of the planet’s orbit, which enables the measurement of the planet’s actual mass. Why is the radial velocity method biased towards high mass […]

Can a body have zero velocity and still acceleration give example?
Can a body have zero velocity and still acceleration give example? Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up.
