Hi!

We call these stars <em>main sequence </em>stars. Main sequence stars actually make up around 90% of the stars in our universe!

An interesting thing to note is that our sun is actually a <em />yellow dwarf star, which is a <em>small </em>main sequence star.

Hopefully, this helps! =)

Harman [31]

Let us consider body moves a distance S due to the force F.

Hence the work by the body W = FS

If the force is not along the direction of displacement,then the work by a body for travelling a distance S will be -

                                       W=[ Fcos\theta]*S  where    Fcos\theta is the component of the force along the direction of displacement.

                                  Hence\ W= FScos\theta

                                                        = F.S

As per the question the power P is given as -

                                                  P=\frac{W}{\delta t}

                                                         =\frac{F.S}{\delta t}

                                                         = F.\frac{S}{\delta t}

                                                         = \ F.V

Hence alternative definition of power P = F.V
