By comparing the object with a stationary object. For instance, we are standing apparently still on earth, yet by comparing our position against the sun and stars, we have proof that the earth is actually moving.
velocity of the object
object's velocity
If you know the speed and direction of the object's motion, then you know its velocity.
The magnitude and direction of the object's velocity vector.
no not really but it for shure does need a motion to this you know like a motion.
you now this because speed is how fast an object is ''moving'' and motion is when an object is ''moving''
you need to know where the object is and where it is after a period of time
