Final answer:
In physics, for a plate to move, the driving forces must exceed the resisting forces. This is explained by Newton's laws of motion and is related to the concept of force and motion. Examples can be given to illustrate this principle.
Step-by-step explanation:
In physics, for a plate to move, the driving forces must exceed the resisting forces. This concept is related to the study of force and motion. According to Newton's laws of motion, an object will remain at rest or move at a constant velocity unless acted upon by an unbalanced force. So, if the resisting forces (such as friction) are greater than the driving forces, the plate will not be able to move.
For example, if you try to push a heavy box across a rough floor, the friction between the box and the floor will act as a resisting force. If the force you apply is not greater than the friction force, the box will not move.
Therefore, it is necessary for the driving forces, such as applied force or external forces, to be greater than the resisting forces, such as friction or other opposing forces, in order for a plate or any object to move.
The question refers to the forces involved in moving an object, particularly a plate, across a fluid or a surface, in the context of Physics. To set an object in motion on a surface, such as a top plate over a bottom plate separated by a fluid, a force must be applied that exceeds the frictional force opposing the motion. According to scientific principles, work is done when a force causes a displacement in the object in the direction of the applied force. In this scenario, the force required to move the plate is affected by factors such as the velocity (v), the area of the plate (A), the distance between the plates (L), and the coefficient of viscosity (η). The resisting forces like friction are influenced by the roughness of the surfaces, adhesive molecular forces, and other material properties. For the plate to move at a constant velocity, the driving force applied must be calculated considering all these dependent factors.
