Can the relative velocity of two bodies be greater than the absolute velocity of either?

Yes it can be!!!
If two cars on a straight road head directly toward each other at a speed of 60mph (relative to the road), the velocity of one relative to the other is 120mph.
This example arbitrarily uses the road as the reference for each car's speed, but there really is no such thing as "absolute velocity" and both cars would have a velocity of about 1000mph relative to the center of the Earth.
According to Einstein's principles of "Relativity" all velocity is relative.

What is the difference between static friction and sliding friction?
Sliding friction is always less than the static friction by small amount.
Explain the difference between absolute and relative power.?
In exercise physiology, the difference between absolute and relative expressions of anaerobic power is that absolute mean power is calculated using the constant rate of falling bodies while relative mean power is calculated using a person's body weight to be able to compare power produced by that individual to their own body weight.
What is relative acceleration?
relative acceleration between two bodies in motion is the vector substraction of the acceleration of that bodies.
What is relative velocity for two bodies A and B with velocities Va and Vb in the same direction?
If the velocities are equal from my point of view, then I see them both moving at the same speed and in the same direction. That means that from the point of view of an observer riding on either body, the other one is standing still. Their relative velocity is zero. This is exactly the situation with a passenger and the book she's reading, both in an airliner flying west at 400 mph.
Why do the velocity of free falling bodies not change?
The velocity of free falling bodies do change However there are some exceptions like a free falling rain drop Please mention the case of which you want to know too
The more massive is an object and the smaller is its radius the greater or smaller is the escape velocity from it?
For two bodies with equal radius, the more massive has the greater escape velocity. For two bodies with equal mass, the one with smaller radius has the greater escape velocity. Both conditions listed in the question indicate greaterescape velocity.

What occurs when any two objects change position relative to each other?
when two bodies change their positions with time, it's termed as motion and if the motion continues it may begin to have velocity,acceleration etc

Is momentum of heavier bodies is greater than lighter bodies?
Yes.
Why are africans tall and slender?
Because long, thin bodies, presenting a greater surface area relative to volume, are better able to dissipate body heat respect to rounder bodies that instead are better suited to preserve body heat. The round bodies of the Inuit of the Arctic and the tall, slim bodies of some African population are examples of natural selection at work.
Is the world spinning really fast right now?
Really fast is a relative term. But at the equator, relative to the other bodies in the solar system, the earth is moving at a rate a little greater than 1000 miles per hour. Most would consider that really fast.

What is the name for the relative angle between 2 celestial bodies?
aspect
What is the meaning of formula for resultant velocity?
There are several layers of complexity to resultant velocity of a colision based on the assumptions used. In a cohessive colision, two or more bodies colide and fuse into one. The resultant velocity is the speed and direction the new body will travel due to the momentum of the original bodies. In a non-cohessive colision, two or more bodies colide, but subsequently rebound away from each other based on the area of contact and momentum of the relevant bodies. The resultant velocities are the speed, direction, and rotation the bodies after the crash.
