what is the concept of minimum force?
611438
minimum force. Those minimum actions, including the use of armed force, sufficient to bring a situation under control or to defend against hostile act or hostile intent. All actions must cease as soon as the target complies with instructions or ceases hostile action.

Newton's second law of motion provides an explanation for the behavior of objects when forces are applied to the objects. The law states that external forces cause objects to accelerate, and the amount of acceleration is directly proportional to the net force and inversely proportional to the mass of the object.

Basic Principle of Hovercraft The basic principle of the hovercraft is that moving an object from the ground using air, then it requires less force to move the object. Because the object does not have any contact with the ground, then the surface tension will get reduced.

If you mean can the magnitude (the size) of a force be negative then the answer is no. There is no meaning to the idea of a force value less than zero force. HOWEVER: Force is a vector. If you define a positive DIRECTION for force then a negative force is simply in the opposite direction.

Newton's second law of motion describes the relationship between force and acceleration. They are directly proportional. If you increase the force applied to an object, the acceleration of that object increases by the same factor. In short, force equals mass times acceleration.

The difference between Minimal and Minimum. When used as adjectives, minimal means the smallest possible amount, quantity, or degree, whereas minimum means to the lowest degree. Minimum is also noun with the meaning: the lowest limit. ... The smallest possible amount, quantity, or degree.

The work done by external. forces (Wext) is related to the total mechanical energy of the initial (TMEi) and of the total energy of the. final state (TMEf) of a system as follows: TMEi + Wext = TMEf.

The principle of virtual work states that in equilibrium the virtual work of the forces applied to a system is zero. Newton's laws state that at equilibrium the applied forces are equal and opposite to the reaction, or constraint forces. This means the virtual work of the constraint forces must be zero as well.

Explanation: Normal force is defined as the force that a surface exerts on an object. If the object is at rest, net force on the object is equal to zero; therefore, the downward force (weight) must be equal to the upward force (normal force). Since weight acts in the downward direction it will be negative.

The normal force is just one component of the contact force between objects, the other component being the frictional force. ... In many cases the normal force is simply equal to the weight of an object, but that's only when the normal force is the only thing counteracting the weight.

About Motion & Force for Kids They explain that any change from moving to not moving or vice-versa requires an unbalanced force, and that the amount of motion is proportional to the size of the force and inversely proportional to the mass of the object.

a = f (net) / m, where a = acceleration, f (net) = the net force acting on the object, m = the mass of the object.

Newton's Second Law "If the net force on an object is not zero, the object will accelerate. The direction of the acceleration is the same as the direction of the net force. The magnitude of the acceleration is directly proportional to the net force applied, and inversely proportional to the mass of the object."

The four basic forces are the gravitational force, the electromagnetic force, the weak nuclear force, and the strong nuclear force.

Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

A: Force is mass times acceleration, or F= m x a. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass. This is Newton's Second Law of Motion.
