The combination of all of the forces acting on an object is called the A. net force B. total force 6. An object is in motion when A. the object changes position relative to a stationary reference point. B. you observe the object move. 3. If the net force acting on a stationary object is zero, then the object will A. Accelerate B. remain at rest 7. An object that changes position relative to a reference point is A. stationary B. in motion 4. If the net force on an object is zero then the object has 8. Average speed can be represented by the mathematical expression A. balanced forces B. unbalanced forces A. distance/time B. distance x time
