Explain your answer.

9.

Why does constant velocity indicate NO net force?

net forces are connected to velocity, not acceleration

constant velocity means that there is acceleration, and therefore means that there is no net force

for something to be moving at a constant velocity means there must be a force acting upon it somewhere (Mr. Fischers Example of the Laptop Case)

constant velocity means no acceleration, and for there to be a net force there must be acceleration
