if the angular momentum of planet is constant when its orbiting around the sun then velocity X radius is a constant vr=constant but if we consider the velocity and distance from the sun of the planet in an elipticall orbit to be v and r the centrepital force is provided by gravitational...

acc to Newtons gravitational theory f=GmM/r^2 and the distance r is taken from the centre of mass of the object so hypothetically if there was a flat rectangular planet gravity would be highest at the centre of the rectangular planet and if we stand away from the center gravitational pull...

well the first ball ends up with a velocity of 2w-v not 2w+v so if the velocity of the small ball is much larger than the larger ball it wud bounce back and the velcity of large ball will remain w equation : final velocity of first ball=(m-M)v/m+M +2Mw/m+M since M is much larger...

angular momentum trouble! since the angular momentum of a particle moving about a fixed point (axis) is given by L=r X p= r X mv where; L=angular momentum r= distance from the axis p=linear momentum of the particle m= mass of the particle v= linear velocity of the particle but if the...

why does planets have eliptical orbits (pls explain -not mathematically if posssible)

what does the direction of torque signify (if a force is apllied to a wrench in the x-axis and the wrench lies on y-axis the nut also rotates in the xy pane but the direction of torque is in the z axis what does this direction show)

does the angular velocity increases or the linear velocity increases when the radius of a rotating body from the axis decreases

pls explain what is angular momentum and if possible explain why velocity increases when radius decreases (not mathematically)
