The best statement to describe the effect of the force applied to a moving object is:
- The force will cause a change in the momentum of the object.
This is because momentum is defined as the product of an object's mass and its velocity, and any net force acting on an object will result in a change in its velocity (and thus momentum) according to Newton's second law of motion (F = ma). The other options may be true in specific scenarios but are not universally applicable as is the case with momentum.
