A force is a push or a pull of an object that allows the object to have motion. The force of an object is measured in newtons (N). There are always something that exerts a force. For example, when you pull up your covers, the object that is exerting the force are your blankets. Sometimes, determining what the object is exerting the force is harder. Net forces are the total amount of force that is on an object. If the forces move in the same direction, the net force would be determined by adding the forces together. An example is when you and your sister are pushing a desk. Your sister’s force on the desk was 20 N left and your force on the desk was 25 N left, the net force would be 45 N to the left. If the forces move in different directions, the net force would be determined by subtracting the smaller force away from the larger force. The final net force would go in the direction of the larger force’s direction. When the net force is 0 N, then the forces are balanced. A balanced force would not let the object start moving or stop moving. If the object doesn’t have a net force of 0 N, then the forces of the object are unbalanced.
