Question 1

What is how to find normal force?

Accepted Answer

The normal force is the force exerted by a surface on an object in contact with it. It's always perpendicular to the surface. Here's how to find it:Understanding the Concept: The normal force is a contact force that prevents an object from passing through a surface. It's a reaction force in accordance with Newton's Third Law.Free Body Diagram (FBD): Draw a free body diagram of the object. Include all forces acting on the object, such as gravity (weight), applied forces, friction (if applicable), and, of course, the normal force.Identify Relevant Axis: The normal force is usually (but not always) along the y-axis (vertical). Choose an appropriate coordinate system.Apply Newton's Second Law: Apply Newton's Second Law (ΣF = ma) along the axis perpendicular to the surface. This usually means ΣFy = may.Solve for Normal Force:Horizontal Surface, No Other Vertical Forces: If the object is resting on a horizontal surface and there are no other vertical forces acting on it, the normal force (N) is equal to the weight (mg) of the object: N = mg.Horizontal Surface, Additional Vertical Forces: If there's an applied force pushing down on the object (Fa_down), the normal force increases: N = mg + Fa_down. If there's an applied force pulling up on the object (Fa_up), the normal force decreases: N = mg - Fa_up. Make sure , because otherwise the object would be accelerating upward and no longer in contact with the surface.Inclined Plane: On an inclined plane, the normal force is equal to the component of the weight perpendicular to the plane. If the angle of inclination is θ, then N = mg * cos(θ).Acceleration: If the object is accelerating vertically (ay ≠ 0), then ΣFy = may.  For example, if the object is accelerating upward, N - mg = may, so N = mg + may.Units: The normal force is measured in Newtons (N).
