Reaction force is the force exerted by an object in response to an action or force applied to it. It is equal in magnitude but opposite in direction to the applied force, according to Newton's Third Law of Motion.
To calculate reaction force, you need to first identify the applied force and the object that is experiencing the force. Then, using Newton's Third Law of Motion, you can determine the reaction force by setting it equal to the applied force but with the opposite direction.
The unit of measurement for reaction force is typically Newtons (N) in the International System of Units (SI). However, other units such as pounds (lbs) may also be used in some cases.
The magnitude of reaction force can be affected by various factors, including the mass of the object, the speed and direction of the applied force, and external factors such as friction and air resistance.
Calculating reaction force is important for understanding and predicting the behavior of objects in motion. It can also help in designing and building structures and machines that can withstand and properly distribute forces acting upon them.
