Depends entirely on your frame of reference!
If you are in a car traveling along side it at 50 ms, the car will appear to be standing still.
If you are going the opposite direction at 50 ms, it will appear to be traveling at 100ms.
When an object is observed from a moving frame of reference, its velocity may appear different due to the relative motion between the observer and the object. This change in velocity is known as relative velocity, and it can be calculated by considering the velocities of both the object and the observer.
In an inertial frame of reference, objects move at a constant velocity or remain at rest without any external forces acting on them. In a non-inertial frame of reference, objects may appear to accelerate or experience fictitious forces due to the frame itself accelerating or rotating.
The motion of a train on a moving track depends on the reference frame you choose. In the train's frame of reference, it may appear stationary or moving at a constant speed. However, in an external, stationary frame of reference, the train would appear to be moving at a different velocity that combines the train's speed with the speed of the track.
Direction and velocity are relative to a frame of reference, meaning they are described based on the observer's perspective. Direction indicates the path of motion with respect to the frame of reference, while velocity specifies how quickly and in what direction an object is moving within that reference frame.
An inertial reference frame is a frame of reference in which an object not subject to external forces moves at a constant velocity. An absolute reference frame is a hypothetical frame of reference that is fixed in space and in which all other frames of reference are measured. Inertial reference frames are relative to each other, while the absolute reference frame provides a universal standard of motion.

usually the motion of your frame of reference is 0. When you are in a train going 50 mph, your frame of reference would be you are going 0 mph and the tracks are traveling at -50 mph.
You would add the characteristics of the original reference frame itself. For example, if you know the walking speed of a man on a bus with respect to the bus and you want to know the velocity of the man with respect to the ground, find the vector sum of the man's velocity w.r.t. the bus and the bus' velocity w.r.t. the ground. If one reference frame is not a subset of the other, solve first for a reference frame they have in common. For example, if you want to know the velocity of the man in the first example with respect to a passing truck, find his velocity with respect to the ground first. Keep in mind that "forward" can mean different directions in different reference frames.
No, an inertial reference frame is not an absolute reference frame. It is a frame of reference in which an object either remains at rest or moves with constant velocity in a straight line, but it is not considered absolute as its motion can be affected by external forces.
The most common frame of reference in physics is the inertial frame of reference, where an object is considered to be at rest or moving with constant velocity. Observers in different inertial frames will agree on the laws of physics governing the motion of objects.
Work is force X distance travelled. Force is mass x acceleration. Aceeleration depends on the frame of reference from which one is measuring it. Hence work done depend on the frame of reference from which one is measuring it. QED
