when their velocity vectors are in the same direction and same magnitude
Just like everything else, that would depend on who is looking at the watch, and how the observer is moving relative to it. To the person wearing the watch, it would appear perfectly normal, as it tick-tocked regularly and the hands moved slowly. But to a stationary observer ... one with respect to whom the watch is moving at light speed ... the watch would appear to have stopped --- just like the heartbeat of the person wearing it!
a glacier that stays in one spot ( stationary )answer 2 the above is OK, but these stationary ice fields are usually called ice plateaus. And they are plateaus because they don't move; otherwise they would be sloping. Actually they may have a very slight slope, but they will appear flat.
Pulsars appear to flash on and off because they emit beams of light in a specific direction, similar to a lighthouse. As the pulsar rotates, the beam of light sweeps across our line of sight, causing the pulsar to appear to pulse or flash.
The order of a reaction with respect to ClO2 is determined by the exponent of ClO2 in the rate law expression. If the rate law is of the form rate = k[ClO2]^n, then the order with respect to ClO2 is n. This value can be determined experimentally by measuring how changes in the concentration of ClO2 affect the reaction rate. If the concentration of ClO2 does not appear in the rate law, then the order with respect to ClO2 is zero.
The North Star, or Polaris. This star remains nearly stationary in the sky while all other stars seem to rotate around it due to the Earth's rotation on its axis.
Airplanes can appear to be stationary to someone on the ground, but they cannot be stationary in the air.
The motion of a pulse with respect to the source depends on the relative motion between them. If the source and pulse are both stationary, the pulse moves away from the source at a constant speed. If the source is moving towards the pulse, the pulse will appear compressed, while if the source is moving away, the pulse will appear stretched.

The Earth orbit in which satellites appear to be stationary is called the, "Geostationary Orbit". Some call it a synchronous orbit.

Stationary objects are objects that are not moving or changing position relative to a reference point. They appear to be at rest and have no velocity. Examples of stationary objects include a chair, a building, or a mountain.
No. Assuming there are no eddies or crosscurrents, and it is not blown in a different direction by the wind, a leaf in a stream is being moved by the water, and would display little motion with respect to the water, as compared to its motion with respect to things not in the flowing stream.
A stationary wave is also known as a standing wave. It is formed by the interference of two waves traveling in opposite directions but with the same frequency and amplitude. Standing waves appear to be stationary because the crests and troughs remain in fixed positions.
If something appears to be moving to the left of you, it means that its motion is directed towards your left side relative to your own position. This can occur if the object is actually moving to the left, or if you are moving to the right while the object remains stationary. Another possibility is that the object is stationary, but you are moving to the left.
Stars are not twinkling really. It is because of the atmosphere of the earth due to which they appear twinkling. However if they are seen from above the atmosphere of earth then they appear stationary.
A static frame is a fixed reference point with respect to which motion is described, while a moving frame is a reference point that is in motion relative to the objects being observed. In a static frame, objects appear stationary, while in a moving frame, objects may appear to be moving even if they are stationary in the static frame.
