# What is the amount of force needed to move an object in space?

Consider an object placed in space, where there is no gravity. What is the amount of force needed to move the object by one unit length?

How does that relate to the mass of the object and the time spent?

• Any force applied to an object will result in acceletration with no friction see Newton's 2nd law where F = ma: have a look at physicsforums.com/threads/… – spk578 Dec 23 '15 at 10:19

Because space is frictionless, you can use basic physics to calculate the information you need. $F=ma$, and from $a$ you can derive the object's speed and position over time.
