Sometimes that type of force can be calculated (like the force between a book and a table on which it is sitting) and sometimes it can't. The force you described can't be calculated, only measured.
Place a scale between your hands and the wall.assuredlonewo said:How can you measure it?
The force of an object that is not accelerating can be calculated using the formula F = m x a, where F is the force, m is the mass of the object, and a is the acceleration. However, since the object is not accelerating, the value of a will be 0, so the force can simply be calculated by multiplying the mass by 0. This means that the force of an object that is not accelerating is 0 Newtons.
Force and acceleration are two different physical quantities. Force is a measure of the push or pull on an object, while acceleration is a measure of how quickly the object's velocity changes. Force can cause acceleration, but acceleration can also occur without a force acting on the object (e.g. in the case of free fall).
Yes, an object can have a force acting on it without accelerating. This is possible when the force acting on the object is balanced by an equal and opposite force, resulting in a net force of 0. In this case, the object will remain in a state of constant velocity (or at rest).
The mass of an object is directly proportional to the force acting on it. This means that the greater the mass of an object, the greater the force needed to accelerate it. For example, a heavier object will require more force to be pushed or pulled than a lighter object.
The SI unit for force is the Newton (N), named after Sir Isaac Newton. Other common units for force include pounds (lb) and kilograms (kg). Force can also be measured in terms of its components, such as tension in Newtons (N) or friction in Newtons (N).
