The friction force is ## \mu_s N ## where N is the normal force. The normal force here is ## not ## mg. Do you see why?taotao said:

Newton's laws help in finding an expression for the angle of inclination by providing a framework for understanding the forces acting on an object. By applying Newton's laws to the forces acting on an object on an inclined plane, we can determine the relationship between the angle of inclination and the forces involved.
The first law of motion states that an object at rest will remain at rest and an object in motion will continue in motion at a constant velocity unless acted upon by an external force. This law is relevant in finding the angle of inclination as it helps us understand the forces acting on the object on an inclined plane and how they affect its motion.
The second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. By applying this law to the forces acting on an object on an inclined plane, we can determine the acceleration and use it to find the angle of inclination.
The third law of motion states that for every action, there is an equal and opposite reaction. This law helps us understand the relationship between the forces acting on the object on an inclined plane and how they affect its motion. By considering the reactions to the forces, we can find the angle of inclination.
Yes, there are many practical applications of using Newton's laws to find the angle of inclination. For example, engineers use this concept to design ramps and inclined planes for different purposes, such as wheelchair ramps, ski slopes, and car ramps. It is also useful in understanding the motion of objects on hills or inclines in everyday life.
