    The purpose of a simple machine is to make work easier by allowing for a push or pull to occur over an increased distance.   

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A simple machine is designed to reduce the amount of force needed to perform a task by increasing the distance over which the force is applied. This allows for a smaller force to be exerted over a longer distance, making the work easier to accomplish. Therefore, the statement that the purpose of a simple machine is to make work easier by allowing for a push or pull to occur over an increased distance is true.

    The pivot point of a lever is called a ____________________.

    Correct Answer
    fulcrum
    Explanation
    A fulcrum is the pivot point of a lever. It is the point around which the lever rotates or balances. The position of the fulcrum determines the mechanical advantage of the lever.

    A rope, a wheel with a groove in it and a weight make up this simple machine. You can pull down on the rope to lift the weight.  

    • Incline plane

    • Screw

    • Pulley

    • Wheel and Axle

    Correct Answer
    A. Pulley
    Explanation
    A pulley is a simple machine that consists of a wheel with a groove and a rope. In this scenario, the rope is pulled down, which causes the wheel to rotate and lift the weight. This demonstrates how a pulley can be used to lift heavy objects by applying a smaller force over a longer distance. The other options, incline plane, screw, and wheel and axle, do not involve the use of a rope and wheel with a groove, and therefore do not fit the given situation.

    The bottom of a light bulb is what type of simple machine? - ProProfs

    The bottom of a light bulb is what type of simple machine?

    • Wedge

    • Complex machine

    • Screw

    • Pulley

    Correct Answer
    A. Screw
    Explanation
    A screw is considered a simple machine because it can be used to amplify force or change the direction of force. In the case of a light bulb, the bottom part that is screwed into the socket acts as a screw. By twisting it, the screw creates a secure connection and holds the bulb in place. This demonstrates the basic principles of a simple machine, making the correct answer "screw".

    What 2 simple machines make up a pair of scissors? - ProProfs

    What 2 simple machines make up a pair of scissors?

    • Wedge and lever

    • Screw and incline plane

    • Pulley and wheel and axle

    Correct Answer
    A. Wedge and lever
    Explanation
    A pair of scissors is made up of two simple machines: a wedge and a lever. The blades of the scissors form a wedge, which helps to separate and cut materials. The handles of the scissors act as levers, allowing us to apply force and control the movement of the blades. Together, these two simple machines work in tandem to create the cutting action of a pair of scissors.

    A heavy object could be rolled up this simple machine, instead of lifting it straight up. Using this simple machine can save effort, although the object must usually cover more distance if this simple machine is used.   

    • Screw

    • Simple Machine

    • Wedge

    • Incline plane

    Correct Answer
    A. Incline plane
    Explanation
    An incline plane is a simple machine that allows a heavy object to be rolled up instead of being lifted straight up. By using the incline plane, less effort is required to move the object compared to lifting it directly. However, the object must usually cover more distance when using the incline plane. Therefore, the incline plane is a useful simple machine for reducing effort in certain situations.

    What is the definition of a screw?  

    • An inclined plane wrapped around a cylinder.

    • Something that holds wood together.

    • A screw is not a simple machine.

    • A flat sloped surface.

    Correct Answer
    A. An inclined plane wrapped around a cylinder.
    Explanation
    The correct answer is "an inclined plane wrapped around a cylinder." This definition accurately describes a screw as a simple machine consisting of an inclined plane in the form of a spiral thread wrapped around a cylindrical shaft. This design allows a screw to convert rotational motion into linear motion, making it useful for various applications such as holding objects together or lifting heavy loads.

    How does a ramp make work easier?   

    • You can ride your skateboard up it, rather than walking up the stairs

    • it helps hold a door open so I don't have to.

    • It spreads the work out over a longer distance.

    Correct Answer
    A. It spreads the work out over a longer distance.
    Explanation
    A ramp makes work easier by spreading the work out over a longer distance. When you use a ramp, you can exert a smaller force over a longer distance to move an object, instead of exerting a larger force over a shorter distance. This reduces the amount of force required to do the work, making it easier to accomplish.
