What is the shape of force versus time graph for an object in linear motion?

I was plotting it but I got force as zero in between some time intervals, just wondering how could force be zero if an object is in motion?What is the shape of force versus time graph for an object in linear motion?If an object is moving at a constant velocity, then the acceleration of that object is zero (acceleration is the measure of how fast the velocity is changing, if the velocity is unchanging, acceleration must be zero). By Newton's Second Law, if the acceleration of an object is zero, the net force on that object must also be zero.



Newton's First Law also mentions this concept. Once an object is in motion it'll keep moving at the same velocity forever unless a force acts on that object. Now there must be some force acting on the object initially to get it moving, but once it's moving you can cut off all the forces on the object and it'll go forever (not really a practical experiment though since there are always forces like friction and gravity that cause the motion to stop).
