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.
What else can I help you with?
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 formula used in measuring force?
The formula used to calculate force is: Force = mass x acceleration. This formula describes how a force is generated when an object with mass is accelerated.
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.
The formula used to find force is?
The formula used to find force is F = m * a, where F is the force, m is the mass of the object, and a is the acceleration.
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 formula of newton's third law of motion?
The third law states that for every action (force) in nature there is an equal and opposite reaction. YOUR WELCOME PPLZ!!!!!!! xD for every action there is a reaction
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 formula of the frictional force?
Friction force hasn't a chemical formula.
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
What is the formula used in measuring force?
The formula used to calculate force is: Force = mass x acceleration. This formula describes how a force is generated when an object with mass is accelerated.
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.
The formula used to find force is?
The formula used to find force is F = m * a, where F is the force, m is the mass of the object, and a is the acceleration.
