Do you have an example relating to your question?
For example, as the Earth revolves around the sun is the 'force' on each different? Are the 'speeds' different? Would the force on each be different than the first case if the earth were plunging towards the sun? How about a pair of photons travelling along side by side in the same direction compared with travelling in opposite directions?
A bunch of the 'latter' answers here are pretty far afield from your question.... as experts are discussing stuff with each other.
