Choose the 200 kg refrigerator. set the applied force to 400 n (to the right). be sure friction is turned off. what is the net f

The refrigerator experiences a net force of 400 N directed to the right. The net force, also known as the resultant force, is the total of all forces impacting an object in both x and y directions. In the context of vertical forces, the gravitational force acts downwards while the normal force acts upwards, preventing the object from falling. On the horizontal axis, the applied force propels motion to the left or right, in contrast to friction that resists movement. In this scenario, we can assess the forces affecting both axes: For the x-axis: Gravitational force = -1960 N Normal force = +1960 N Net force = -1960 N + 1960 N = 0 Given that the gravitational force results from the object’s weight (mass multiplied by gravitational acceleration at 9.8 m/s²) and since the object remains stationary, these forces balance each other. Therefore, the normal force equals the downward gravitational force but in the opposite direction. Evaluating forces along the y-axis shows a net force of 0, indicating no upward or downward movement. For the y-axis: Applied force = +400 N Friction = 0 Net force = +400 N + 0 = +400 N The applied force is classified as +400 N, signifying rightward direction. Because friction is acknowledged to be non-existent (or turned off), the result is an overall net force of +400 N acting towards the right.

The net force acting on the refrigerator is calculated by summing all forces influencing the body, accounting for the direction of each force. In simpler terms, the net force is the vector sum of all acting forces. The refrigerator's mass is given, as well as the acting force. As friction is absent on the surface, this means no opposing force hinders the refrigerator's movement. The net force's horizontal and vertical components must both be assessed. Regarding vertical forces, the weight, acting downwards, is balanced by the normal force, pushing upwards, originating from the ground. Consequently, these forces offset each other. Given the vertical equilibrium, we note the net force in this direction is zero. In horizontal terms, with friction absent, there exists no force to halt the refrigerator's motion. Similarly, an applied force encourages movement. Hence, the net force governing horizontal movement is identified accordingly.
