List of top Physics Questions on Keplers Laws

Kepler's second law (law of areas) of planetary motion leads to law of conservation of

A satellite revolves around the earth of radius \(R\) in a circular orbit of radius \(3R\). The percentage increase in energy required to lift it to an orbit of radius \(5R\) is
Binary stars \(m_A, m_B\) move in circular orbits. Compare their time periods.
A geo-stationary satellite is one which:
If a new planet is discovered rotating around sun with the orbital radius double that of the earth, then what will be its time period? (in earth's days) (Take $\sqrt{2}=1.4$ )
The longest and the shortest distance of our planet from sun is and $R_1$ and $R_2$. Distance from sun when it is normal to major axis of orbit is .
In planetary motion the areal velocity of position vector of a planet depends on angular velocity ( $ \omega $ ) and distance of the planet from the sun (r). If so the correct relation for areal velocity is
The earth moves in an elliptical orbit with the sun $S$ at one of foci as shown in the figure. Its rotational kinetic energy is maximum at the point
A planet is moving around the sun in an elliptic orbit. Its speed
A satellite is revolving around the earth in a circular orbit of radius $4$ times that of the parking orbit. The time period of the satellite is :
As shown in figure, $a$ planet revolves in elliptical orbit around the sun, where $K.E.$ of the planet is maximum :
The rotation period of an earth satellite close to the surface of the earth is 83 minutes. The satellite in an orbit at a distance of three times earth radii from 2 jts surface will be
The radius vector, drawn from the Sun to a planet sweeps out equal areas in equal lines. This is the statement of
The earth revolves around the sun in one year. If distance between them becomes double, the new time period of revolution will be
The earth moves in an elliptical orbit with the sun S at one of foci as shown in the figure. Its rotational kinetic energy is maximum at the point
