Answer:
The force required to maintain an object at a constant velocity in free space is equal to Zero.
There is no force required to maintain an object at a constant velocity in free space.
Laws of motion:
- Newton's First Law of motion states that a body under motion will continue to be under motion until there is any external force is applied.
- In practical conditions, there is a frictional force acting on any moving object, opposite to the motion, which tends to decelerate the object, so to keep the object under motion with a constant velocity a force equal and opposite to the frictional force is needed so that the net force on the object is zero.
- But in ideal conditions such as free space, there is no opposing force or frictional force, so there is no need of applying any external force to maintain the object at a constant velocity.
