Final answer:
An inclined plane is a simple machine in Physics that reduces the force needed to raise objects by spreading the work over a larger distance.
Step-by-step explanation:
The correct answer is option Physics. An inclined plane is a simple machine that facilitates work by allowing a force to be applied over a longer distance, reducing the magnitude of the force needed to lift an object to a higher elevation.
Pushing a cart up a ramp as opposed to lifting it vertically is a practical example. The work done is the same in both scenarios, assuming there is no significant work done by friction. This principle was likely utilized in historical constructs such as the Egyptian pyramids.
In modern times, inclined planes are everywhere, serving as ramps for accessibility, skateboarding parks, and even in the design of tools like knives, which operate on the principle of two inclined planes forming a wedge.
The inclined plane is a simple machine consisting of a sloping surface that connects lower and higher elevations. It is used to make work easier by reducing the amount of force required to move an object.
When pushing a cart up an inclined plane, the applied force is less compared to lifting the cart straight up to the top using a ladder.
This is because the inclined plane allows the force to be exerted over a longer distance, making it easier to move heavy objects. Examples of inclined planes in real life include ramps and highways.
It was historically used in the construction of the Egyptian pyramids and is now seen commonly in various tools and surfaces.
