Oct 14, 2020 · Reaction force refers to its physical content - a response to the action of an object. Normal force refers to its direction - it is perpendicular to the surface. Many forces can be normal forces and/or reaction forces, and do not necessarily be both.
In mechanics, the normal force is the component of a contact force that is perpendicular to the surface that an object contacts. [1] In this instance normal is used in the geometric sense and means perpendicular, as opposed to the common language use of normal meaning "ordinary" or "expected".
Feb 20, 2022 · When objects rest on a surface, the surface applies a force to the object that supports the weight of the object. This supporting force acts perpendicular to and away from the surface. It is called a normal force, \(T\) When objects rest on a non-accelerating horizontal surface, the magnitude of the normal force is equal to the weight of the ...
Learn about and revise contact and non-contact forces, the difference between weight and mass, and Newton's third law with GCSE Bitesize Physics.
Define normal and tension forces. Apply Newton's laws of motion to solve problems involving a variety of forces. Use trigonometric identities to resolve weight into components. Forces are given many names, such as push, pull, thrust, lift, weight, friction, and tension.
One important difference is that normal force is a vector, while the newton is simply a unit. Be careful not to confuse these letters in your calculations! You will encounter more similarities among variables and units as you proceed in physics.
