_______________________
n)The vector sum of all force vectors that act on an object__________
o) If the net force on an object is equal to zero the object will remain at rest if it was
at rest if its moving it will remain in motion in straight line with the same constant
velocity this law called ___________

acceleration in the same direction as the force this law called ___________
