An object is moving in the absence of a net force. Which of the following best describes the object’s motion? A. The object will
slow down at a constant rate until coming to rest B. The object will stop moving and remain at rest until acted on by a net force C. The object will continue to move at a constant speed but in a circular path D. The object will continue to move with a constant velocity
D. The object will continue to move with a constant velocity
Explanation:
According to Newton's first law also known as law of inertia, states that an object at rest will remain at rest or, if in motion, will remain in motion at constant velocity unless acted on by a net external force.
Therefore, An object moving in the absence of a net force will continue to move at a constant velocity
Hundreds of millions of comet nuclei forming a spherical region that surrounds the solar system is called Oort cloud.
The Oort cloud revolves at tens of thousands of the distance of the earth from the sun.
Comets are the condensed water and dust particles that orbit around the sun with inward helix leaving behind a tail of vapours and vaporize completely as they get closer to the sun during their revolution around it.
They have a nebulous appearance and extremely elongated orbits.
