Taking a break from hiking up a steep hill, a hiker stands still on the incline. What are the forces acting on the hiker as they stand still?  No forces act on the hiker since they stay at rest  The normal force, the weight, and kinetic friction  The normal force, the weight, and static friction  The normal force and the weight  The normal force, the weight, and the force of gravity

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
