State Kepler’s three laws of planetary motion.

The line that joins a planet and the Sun sweeps equal areas in equal intervals of time.

The square of the time period of revolution of a planet around the Sun is proportional to the cube of the semimajor axis of the ellipse traced by the planet.

1. The Kepler’s laws are:  Kepler’s first law: The orbit of a planet is an ellipse with the Sun at one of the foci.  Kepler’s second law: The line joining the planet...

No. In projectile motion, the horizontal and vertical motion are independent of each other because both motions don’t affect each other.

1. Newton’s laws of motion are not applicable in a non-inertial (accelerated) frame of reference. 2. Newton’s laws are only applicable to point objects. 3. Newton’s laws are only applicable to rigid...
