Question

An object is moving north at a constant speed. A force of 5 N begins to push the object east at the same moment that a force of 5 N begins to push it west. What will happen to the object?

The object will turn toward the west.
The object will slow down and stop.
The object will accelerate toward the east.
The object will continue moving north.

Answer 1

The object will continue moving north.

Reason: the 5 N east and 5 N west forces cancel, giving zero net force. With no net force, there is no acceleration, so the object's velocity remains unchanged (Newton's first law).
