Question

Quizplus · Accepted Answer

Newton's second law states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. Therefore, if a force is applied to a body, it will accelerate in the direction of the force. This means that the body's speed will change (i.e. increase or decrease), not remain constant, while the force is applied.
