It means at least one of these things happens:
-- the object speeds up
-- the object slows down
-- the object keeps moving at the same speed, but turns to a different direction
Velocity is a change in an object's motion OR direction of motion.
The change in an objects position is called motion.
Acceleration
Balanced forces do not change an object's motion.
Objects in motion continuously change position.To change direction, a force needs to act upon them.
uniform motion
it usually does, but if the force is balanced, it will not change the object's motion
unbalanced force(:
That is the definition of motion
