The object does not appear to be staying in one place. Or, it is moving if it's distance from another object is changing.
The object would be moving.
Change of position relative to another object
If you know the speed and direction of the object's motion, then you know its velocity.
you now this because speed is how fast an object is ''moving'' and motion is when an object is ''moving''
velocity
Then we will know the object's velocity.
we can say an object is moving if it changes it constant environmnent or background
The object will be in both rotational and translational equilibrium and will not be moving.
It is easier to push a moving object than an object of the same mass because the weight on the moving object is less and out more.... I know this doesn't quite make sense but email me at oliviabastianich@Gmail.com for a better explenation... i will help in the next 12 hours!
It's important to know that you reference point is moving because if an object is in motion and if it changes position it is relevant to a reference point.
Only if you know your location (the coordinate on the distance scale and the time scale) where "you" are can you infer if the object is moving towards you (the absolute distance to the object is decreasing) or away from you (the distance is increasing).
this object that appears to stay in place is a reference point.
