This holds unless an external unbalanced force is applied on the objects. c) Real-world example of Newton 's First Law: A practical example of Newton’s first law of motion is the motion of a car at a constant speed of 60km/hour with passengers on board. While the car is in motion, the passengers and the driver will move at the same speed. When an emergency brake is suddenly applied, the passengers will be subjected to a forward surge force while the car will stop due to the influence of the external (breaking) force. 2 a) Newton 's Second Law: Newton’s second law states that when a net force is applied to accelerate an object, the object will accelerate in the same direction as the net force. In addition, the acceleration will be directly proportional to the magnitude of the net force and inversely proportional to its mass. b) Explain Newton 's Second Law as if you are talking to a friend: When an object is pushed (applying a net force) so that it moves, the object will move
