orbiting
To be doing work, you must be expending energy or applying effort to achieve a particular task or goal. Work involves the transfer of energy from one object to another, resulting in a change in the state or position of an object.
According to Newton's first law of motion, an object that is in motion will stay in motion. Basically if an object is moving, unless something stops or alters its path in any way, the object will continue to move down the same path.
An object that circles another object is said to be in orbit around it. The object being circled is typically larger and exerts a gravitational force that keeps the circling object in its path. Examples of such objects include the Moon orbiting the Earth and planets orbiting the Sun.
The one doing the revolving is the "orbiting object". It doesn't usually get more specific than that, unless one is referring to a moon or man-made object in orbit around a planet. Those are called satellites. Other orbiting objects include the planets of a solar system around their sun, and the electrons of an atom around its nucleus.
it can be moving at constant velocity or staying still
they are doing something fun like moving around to make elctricity work!!
probably moving to another body of water or somebody abandoned it or moved it.
A horizontal line means that the distance is not changing, therefore we can infer that the object in question is stationary - i.e. not moving.
Indirect object
The desire of an object to keep doing what it is doing is called inertia. "What it is doing" means that it is in motion or at rest,
An object in motion, such as a moving car or a swinging pendulum, has kinetic energy. It is the energy an object possesses due to its motion.
Certainly. Say you have an object that has been falling through the air for a long time, say a skydiver. After falling for a long time, the skydiver will fall at a constant velocity. This is called terminal velocity, and this is when the air resistance pushing up around the skydiver is equal to the force of gravity pulling the skydiver down. The skydiver is not accelerating. By using F= ma, with zero acceleration, there is zero net force. The skydiver is moving as if there are no forces acting on the skydiver.
