What is an inclined plane? What is its use ? Give two examples where it is used.

An inclined plane is a simple machine that consists of a flat surface set at an angle to the horizontal plane. It is one of the six classical simple machines and is widely used to make it easier to move objects by reducing the amount of force required.

The primary use of an inclined plane is to allow objects to be raised or lowered with less effort. By increasing the distance over which an object is moved, the inclined plane reduces the amount of force needed to lift or lower it. It enables humans to overcome the force of gravity by applying a smaller force over a longer distance.

Here are two examples where inclined planes are commonly used:

Ramp: A ramp is a practical application of an inclined plane. It is used to move heavy objects, such as furniture or vehicles, from a lower level to a higher level. By gradually increasing the height, the ramp allows for an easier ascent or descent than lifting the object vertically.

Stairs: Stairs can be seen as a series of inclined planes connected together. They allow people to move between different levels in buildings or outdoor spaces with less effort compared to climbing a vertical ladder. By spreading the height difference over a longer distance, stairs make it more convenient and less physically demanding for individuals to navigate different floor levels.
