Trajectory
That tendency is called inertia. It is a property of matter where objects resist changes in their motion.
It's Newton's first law of motion: "An oject in motion will stay in motion (with the same velocity) until an outside force acts upon it and an object at rest will stay at rest until an outside force acts upon it."
When the wavelength of a spectral line emitted from an object decreases, it moves toward the blue end of the visible light spectrum. This phenomenon indicates that the object is moving toward Earth, a scenario known as blue shift. Common examples include distant galaxies or stars that are moving closer to us.
moving away from us.
A red shift in the spectrum of light from an object indicates that the object is moving away from the observer. This is a result of the Doppler effect, where the wavelengths of light are stretched as the object moves away, causing a shift towards the red end of the spectrum.
an object that is not moving can be in equilibrum. an object moving at a steady speed in a straight line can also be equilibrum.
An object moving at a constant velocity in a straight line. An object at rest or moving at a constant speed in a circular path. An object moving in a straight line with no change in direction.
To determine the celebration of an object moving in a straight line, you can use the formula for velocity, which is distance traveled divided by time taken. This will give you the rate at which the object is moving along the straight line.
Inertia
It's not necessary to specify that the object is moving at a constant speed. Any object with no outside forces acting on it does that. It also continues moving in a straight line.
Inertia causes a moving object to continue moving in a straight line at a constant speed unless acted upon by an external force.
The answer to the question seems to be clearly given within the question. You have said that the object " ... is moving ... " in a straight line. Therefore we conclude that if you have been honest with us, then the object is certainly in motion.
An object moving in a straight line maintains a constant direction from its starting point. An object moving in a curved trajectory is following a path that is not straight and may be influenced by another object's gravitational pull or magnetic field.
If an object is moving away from you and there are no forces acting on it,then it continues moving in a straight line at constant speed.
The object continues moving in a straight line at its current speed.
The object continues moving in a straight line at its current speed.
