What is the formula for NORMAL force?
It is the component of force normal (perpendicular) to the surface.
If it hits perpendicular to the surface , it is the full magnitude of the force.
If it hits at an angle T from perpendicular, then it is |F| cos T

The normal force, denoted by "N," is the force exerted by a surface to support the weight of an object resting on it. The formula for calculating the normal force depends on the situation. Here are a few examples:
1. Flat surface: When an object is resting on a flat surface, such as a table, the normal force is equal in magnitude and opposite in direction to the force of gravity acting on the object. In this case, the formula for the normal force is N = mg, where "m" is the mass of the object and "g" is the acceleration due to gravity (usually taken as 9.8 m/s^2 on Earth).
2. Inclined plane: If an object is placed on an inclined plane, the normal force can be calculated by decomposing the weight force into components parallel and perpendicular to the plane. The perpendicular component of the weight force is equal to the normal force. The formula for the normal force on an inclined plane is N = mg cos(θ), where "θ" is the angle of inclination.
3. Vertical surface: In some situations, an object may be pressed against a vertical wall due to external forces. In this case, the normal force is equal to the force applied to the object by the wall.
To find the formula for the normal force in a specific situation, consider the forces acting on the object and determine how they relate to the support provided by the surface. Use principles of Newton's laws and apply trigonometry if necessary.
