Quick Answer

An inclined plane is, essentially, a ramp. Inclined planes are useful for a wide range of physics experiments, and they can demonstrate basic physics principles about gravity and angular motion.

Full Answer

Some of the earliest experiments about gravity were conducted using inclined planes. One of the curious effects of them is that objects that roll down them have the same speed as objects dropped from the same height, but they take a longer time to reach their ultimate speed.

Ancient cultures used inclined planes for a variety of experiments as well, and they are one of the six classic "simple machines" of the Renaissance period. Without inclined planes, some of the simple rules that govern classical gravitational theory may not have been discovered until later.

Inclined planes also fill a number of practical roles. They were invaluable tools for lifting heavy items since they allow sideways motion to be converted into vertical motion, and many classic structures were built using inclined planes. Their simplicity also makes them popular; simply laying down a flat surface is enough to form an inclined plane, and they can be moved easily. While humans generally call them ramps, inclined planes are still in use in modern buildings.

  • Q:

    How does an inclined plane make work easier?

    A:

    An inclined plane makes work easier by reducing the exertion needed for the job while increasing the distance over which that exertion is maintained. The angle at which a load is lifted determines the amount of exertion needed to lift it. Lifting a load straight overhead requires the most exertion.

    What was Galileo's inclined plane?

    A:

    According to PBS, Galileo's inclined plane was an experiment performed to test the effects of gravity on falling objects. Galileo's inclined plane experiment eventually proved that in the absence of outside forces, gravity causes all objects to fall at an increasing rate.

    What is an inclined plane wrapped around a cylinder?

    A:

    When an inclined plane, a type of simple machine, is wrapped around a cylinder, it forms a screw, which is another type of simple machine. Machines are mechanisms that can make work easier to do.

    What are seven simple machines?

    A:

    The seven simple machines are the inclined plane, wedge, screw, lever, pulley, gear and wheel and axis. The simple machines are non-powered mechanical devices that change the direction or magnitude of a force. Each of these machines is considered to be a simple machine. However, when combined, they are considered a complex machine.
