Hint: In physics, an orbit is an object's gravitationally curved trajectory, such as a planet's orbit around a star or a natural satellite's orbit around a planet. Usually, the term orbital refers to a trajectory that repeats itself, but it may also refer to a non-repeating trajectory. Newtonian mechanics is a good approximation for orbital motion in most cases.
Complete answer:
Newton's first law implies that an object traveling in a straight line will continue to travel in that direction unless it is compelled to change direction by an external force. But what about an object moving in a circle? Some force is at work to move it in a different direction. It's the sun's gravitational force that pulls the planets together. The sun's gravity holds us at about the same distance all the way around. It keeps us from flinging off into the darkness of our solar system.
According to Newton's second law, force equals the shift in momentum per change in time. This law implies that when a force acts on an object, it accelerates in the direction of the force. This rule means that force cannot have components in the direction of velocity in a circular motion. Instead, the force is perpendicular to the object's velocity. As a result, in a uniform circular motion, acceleration is always perpendicular to the trajectory.
We found that the field motion and static motion are the two motions combined to produce an orbit. Field motion differs from collision motion, which is caused by forces such as gravity.In contrast to dynamic motion, static motion occurs when an object moves on or around another moving object that is circular motion.
Note: An orbit is a circular path taken by one object in space around another object on a regular basis. A satellite is a spacecraft that is in orbit. A natural satellite, such as the Earth or the moon, may exist. The International Space Station is an example of a human-made satellite. Remember that an orbit is created when field motion and static motion are combined.
