to an object that stays still
There's no such thing as "motion through space". Motion must be measured relative to another object. So we just measure how fast the other object appears to be moving, and there we go.
When an object is seen moving in relation to a stationary object is called the frame of reference
you now this because speed is how fast an object is ''moving'' and motion is when an object is ''moving''
It means that the object is moving.
mass affects the object that is in motion because it is moving so there for it is moving the same speed
Any moving object can be redefined as a frame of reference at rest, from which all other moving frames can be measured. That's a fundamental precept of Relativity. It's motion is defined only in relation to some other object from which the motion is measured, so reselection as the rest frame is necessary, but once established as a rest frame, it is (for the purpose of measurement) no longer considered to be in motion. Since everything is moving in relation to everything else, any frame can be selected as the frame of reference at rest, with all other motion measured relative to it.

An object's motion in relation to something else
The movement in relation to a frame of reference is called relative motion. A frame of reference is a system of object that are not moving with respect to one another.
When a moving object is pushed in the direction of its motion the speed of the object increases

An object which is moving doesn't need a force to keep it moving.
