When a force of I newton acts on a mass of 1 kg which is able to move freely, the object moves in the direction of force with a/an

According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass [1]. This relationship is mathematically expressed by the formula F = ma, where F represents force, m represents mass, and a represents acceleration. When a force of 1 Newton (N) is applied to a mass of 1 kilogram (kg) that is free to move, the resulting acceleration can be calculated by rearranging the formula to a = F/m. Substituting the given values (1 N / 1 kg) results in an acceleration of exactly 1 m/s². The object will accelerate in the same direction as the applied force. Therefore, the object moves with an acceleration of 1 m/s², making option 2 the correct choice.
