Newton's Third Law states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object exerts a force back on the first object that is equal in magnitude and opposite in direction.
When an object is placed on an inclined plane, it experiences a gravitational force pulling it towards the ground. This force is countered by the normal force of the inclined plane pushing back on the object. According to Newton's Third Law, these two forces are equal and opposite.
Yes, Newton's Third Law can be applied to moving objects on an inclined plane. As the object moves down the inclined plane, it exerts a force on the plane in the direction of its motion. This is balanced by an equal and opposite force exerted by the plane on the object in the opposite direction.
The angle of an inclined plane does not affect Newton's Third Law. The law still holds true regardless of the angle of the plane. However, the angle of the plane can affect the magnitudes of the forces involved, as a steeper angle will result in a greater gravitational force and normal force.
One example is a person sliding down a slide. The person exerts a force on the slide in the direction of their motion, and the slide exerts an equal and opposite force on the person. Another example is a car driving up a hill. The car exerts a force on the hill in the direction of its motion, and the hill exerts an equal and opposite force on the car, allowing it to move up the incline.
