Question
1). What do you know about net force as it relates to Newton's Second Law?
A. A non-zero net force is necessary for an object to stay in motion.
B. If the net force on an object is zero, then the object cannot be moving.
C. If the net force on an object is zero, then the object's velocity vector will not change.
D. If the net force on an object is non-zero, then the object's acceleration vector must be changing.
E. (a) and (b)
F. (c) and (d)
2). An object is moving to the right, but its velocity is decreasing. What can you conclude about the net force on the object?
A. The net force must be pointing to the left
B. The net force must be point to the right
C. There is no net for on the object.
D. (a), (b), or (c) could be correct. More information is needed
