Which statements describe how a machine can help make work easier?
Answer: “A machine can decrease either the input force or the input distance needed to do a given amount of work” is the best statement that describes why a machine is useful.
Which statement describes how a machine can help make work easier quizlet?
Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied.
How does a machine such as a ramp help make work easier a machine can help decrease the input force and the output force?
A machine is any device that makes work easier. Machines make work easier by changing the strength or direction of a force. Machines do not decrease the amount of work that needs to be done, they just make work easier by changing the way it is done.
Which is the result of using a machine?
When you use a machine, you apply force to the machine. This force is called the input force. The machine, in turn, applies force to an object. This force is called the output force.
How does using a ramp make work easier?
A ramp is an example of an inclined plane. Using an inclined plane makes it easier to move an object. It takes less force to move an object in an upward direction on an inclined plane than it does to lift the object straight up. Moving the object up an inclined plane requires moving it an increased distance.
What changes can a machine make to a force?
A machine makes work easier by changing at least one of three factors. A machine may: change the amount of force you exert, • change the distance over which you exert a force, or • change the direction in which you exert a force. Input and Output Forces When you do work, you exert a force over some distance.
Which of the following is a simple machine quizlet?
what is a simple machine? wheel and axel; lever; pulley; wedge; screw; and inclined plane are all examples of >>>>>>.
Which machine makes work easier by increasing the output force?
A wedge is a simple machine that consists of two inclined planes giving it a thin end and thick end. … A wedge makes work easier by increasing the force applied to the object although it applies the force over a shorter distance. This gives the wedge a mechanical advantage greater than 1.
Which simple machine makes work easier by converting a small force exerted over a large distance into a larger force over a smaller distance?
wedge A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance.
How does a pulley make things easier?
How do pulleys make it easier to lift? Pulleys are simple machines that can change the direction of force, making it much simpler for us to move objects. They also increase mechanical advantage when we use multiple pulleys together. This process decreases the amount of force required to lift something up.
How does a machine help us?
Simple machines are useful because they reduce effort or extend the ability of people to perform tasks beyond their normal capabilities. Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever.
How does a machine work?
Machines simply transmit mechanical work from one part of a device to another part. A machine produces force and controls the direction and the motion of force, but it cannot create energy. A machine's ability to do work is measured by two factors. These are (1) mechanical advantage and (2) efficiency.
How simple machines make work easier?
There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied.
How do machines help us?
Simple machines are useful because they reduce effort or extend the ability of people to perform tasks beyond their normal capabilities. Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever.
What is a device that makes work easier?
A machine is any device that makes work easier by changing a force.
What best describes a simple machine?
A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force.
What do simple machines do quizlet?
Tools that make work easier by allowing us to push or pull over increased distances. They give us the advantage by changing the amount, speed, or direction of forces.
What is a device that makes work easy?
A. multiplying forcethe machine applies more force than the user applies to the machine, but the machine applies the force over a shorter distance.
How do machines make our work easier give an example?
Machines make work easier by exchanging force for distance or distance for force. For example, if you need to lift a piano into the back of a pickup…
How do simple machines make work easier Brainly?
Simple machines can actually make more work due to friction. Simple machines make work easier to do by decreasing the force required by increasing the distance over which the work is done.
Why do pulleys make work easier?
How do pulleys make it easier to lift? Pulleys are simple machines that can change the direction of force, making it much simpler for us to move objects. They also increase mechanical advantage when we use multiple pulleys together. This process decreases the amount of force required to lift something up.
How do simple machines make work easier?
There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied.
Why do levers make work easier?
The fixed point of a lever is called the fulcrum. Like other machines, a lever makes work easier by changing the force applied to the machine or the distance over which the force is applied.
What helps make work easier?
Machines make work easier by increasing the amount of force that is applied increasing the distance over which the force is applied or changing the direction in which the force is applied. … That's because a machine doesn't change the amount of work and work equals force times distance.
Do machines make work easy?
Machines make work easier by increasing the amount of force that is applied, or by increasing the distance over which the force is applied, and some machines also help by changing the direction in which the force is applied.
What do machines give us?
As indicated by the math, the main benefit of machines is that they allow us to do the same amount of work by applying a smaller amount of force over a greater distanceA machine can be used to obtain a gain in speed.
How machines have made our life easier?
Using technology allows you to automate tasks, set up reminders, gather receipts, track investments, compare prices, and more. With technology, you won't have to waste your time doing simple financial tasks. With just a few clicks, you can instantly pay your bills.
How machines help us do work?
The basic purpose for which most simple machines are designed is to reduce the effort (force) required to perform a simple task. To achieve this, the force applied must act over a longer distance or period of time resulting in the same amount of work being performed by a smaller force.
How do simple machines help us?
Simple machines are all around us. They help us do so many of our daily tasks, from drawing your blinds in the morning to screwing the cap onto your water bottle. Their purpose is to reduce the amount of force needed to do work. Basically, what this means is they make it easier for us to move and do things.
