First, it depends on your inertial reference frame. If I'm riding in a car holding a book in front of me, in my reference frame the book is stationary, but in the reference frame of a pedestrian the book is moving at the same velocity as the car.
That having been said, an object has moved if its position has changed with respect to time. If we look at an object at two different times, t(1) and t(2), and the object was in two different places, p(1) and p(2), then the object moved at an average speed of [p(2) - p(1)] ÷ [t(2) - t(1)].

How do you know when an object is moving?
Change of position relative to another object
How do you know that all objects in motion have a speed?
you now this because speed is how fast an object is ''moving'' and motion is when an object is ''moving''
When is acceleration become negative?
whe the object slows down
When an air molecule bounces off an object it?
whe a air molecule bounces of and object it puts force in to the object that it bounce of
How do you know that the forces acting on an object are balanced?
The object will be in both rotational and translational equilibrium and will not be moving.
How will you know that an object has kinetic?
The object would be moving.
How do you know if an object is moving.?
The object does not appear to be staying in one place. Or, it is moving if it's distance from another object is changing.
How do you know when an object is moving?
Change of position relative to another object
What the speed and the direction an object are moving?
If you know the speed and direction of the object's motion, then you know its velocity.
How do you know that all objects in motion have a speed?
you now this because speed is how fast an object is ''moving'' and motion is when an object is ''moving''
When you know both the speed and direction of a moving object you know the?
velocity
When is acceleration become negative?
whe the object slows down
What will happened if both speed and direction of the moving object be identified?
Then we will know the object's velocity.
When an air molecule bounces off an object it?
whe a air molecule bounces of and object it puts force in to the object that it bounce of
How do you know if a object is movig ing?
we can say an object is moving if it changes it constant environmnent or background
How do you know that the forces acting on an object are balanced?
The object will be in both rotational and translational equilibrium and will not be moving.
At what point does an object have the greatest kinetic energy?
whe something is rolling down the heil
