Well, if there are no external forces, it means that there is no change. So we can rule out A, C, and D. That leaves us with B and E, which are the correct answers.

To recap: The answers are 'It moves at a constant speed' and 'It moves in the same direction'.

Cindy Shepard · Answer 2

With no external force acting on it, the object moves at a constant speed,

AND it keeps moving in the same direction.

Even if it HAS external forces acting on it, if the external forces are balanced,

cancel each other out, and add up to zero, then the object still moves at a

constant speed, AND it keeps moving in the same direction, just as if there

were NO external force on it at all.
