What is a reaction force and formula?
The idea of a reaction force comes from Newton's third law; "If object A exerts a force on object B ,then object B will exert an equal but opposite force back on A". In many problems some of the forces are considered as the "initiating" force or the applied force. When you consider a force as being applied, like a bulldoser pushing a rock, then the force which must act back , the rock pushing back on the doser, is called the reaction force. Sometimes you don't really have an initiating force but it still convienient to think of one force as the force of interest and the back force as the reaction force. There is no single formula for reaction force since it can apply to any force. For example, the earth attracts you with a force mg (your weight), then you can think of the reaction force as you attract the earth with a force -mg; equal but opposite.
How can there be an unbalanced force on an object if every action has an equal and opposite reaction?
"action/reaction" does not mean " force". "Applying force" is an action, not the force itself. So, applying force will create a reaction, which may or may not balance the applied force.
What is the name often given to the force exerted by the first object on a second object?
The name often given to the force exerted by the first object on a second object is the action force.
What is the reaction force to Centripetal Force within a Centrifuge If centrifugal forces are fictitious?
Always centrifugal is the reaction force for centripetal
What is a force opposite to an action?
Reaction Force.
What force occurs when you apply an action force'?
a reaction force
Is reaction a contact force or field?
A reaction is not a separate force; it is a force that occurs as a response to an action. In the context of contact forces, a reaction force is the force exerted by an object in response to a force acting on it. It is a contact force that arises due to the physical interaction between two objects.
Do action and reaction act on same body?
The force acting on an object "A" from outside is action force , and the reaction force is the force exerted by A to the outside object . Therefore, it is obvious that action force and the corresponding reaction force cannot act on one and the same body.
Are centrifugal force and Reactive Centrifugal force the same thing?
Reactive centrifugal force is not the same thing as centrifugal force. Reactive centrifugal force is the reaction force. It is the reaction force reacting to a centripetal force.
How do you work out the reaction force on something?
According to Newton's 3rd law, every force has an equal and opposite reaction force. Therefore, the reaction force on an object, is the exact same force it applied on another object, with the reverse direction.
What is the reaction force when your foot pushing down on the ground?
The reaction force is equal in magnitude and opposite in direction to the force your foot exerts on the ground. This reaction force is what allows you to push off the ground and move forward.
How is the speed of chemical reaction related to the spontaneity of the reaction?
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
