Machines

Today we learned that work is done when a force causes a change in the position or motion of an object. Like when you race some one, if you want to beat them, then you have to do more work in order to pass that finish line. You can't be first without power! Power is the rate at which work is done. The greater the power, the greater your works done. Most work require alot of power, but the use of machines can make it easier. Machines can range from wheelbarrows, to screwdrivers, to pullies. They all make every thing in our lives easier!

Work, power, mechanical advantages

Today we learned about work, power, and mechanical advantages. Work is done when a force causes a change in the position or motion of an object. Like lifting a water bottle off of the table. Power is the rate at witch work is done. How fast you lifted the water bottle up off the table. Mechanical advantages is when you use machines to help you do work with less force. An example of this is a wedge to split wood.

Work Power and MACHINES

Work is when a force moves something, and the thing that it moves, is doing work because the energy which could be a person pushing is moving the object. Power is the rate at which work is being done. Mechanical Advantage is when you do something with a tool that makes doing the labor a lot easier. Like using your fingers to screw in a screw. And then it would be a lot easier to use a screwdriver. I expect the chapter to be really interesting involving tools.

Work,Power, and Machines

I learned that Work is an object moving due to energy. I also learned that Power is a way of calculating Work in progress, like how much work is done in 3 seconds. And Mechanical advantage is when you have a tool make something alot easier. An example of it. would be using a hammer, to pound in a nail instead of your hand. I was only there for half of the period.

ancer

work power and machanicale advantage the same in the how there used and what they do but power is the the why you use it and how hard it is used. the advantage is we can use it and its esiar for what we use it for. the work power is how much power is used

science

work is the transfer of energy to a body by the app;ication of force that causes the body to move in the direction of the force, power is a quantity that measures the rate at which work is done of energy is transformed, mechanical advantage is a quantity that measures how much a mechine multiplies force or distance
ex: work, lifting weights, power, pushing some thing, mechanical advantage, carring stuff

what is work, power, and mechanical advantage

what is work, power, and mechanical advantage. work is the transfer of energy to a body by the application of a force that causes the body to move in the direction of the force. power is a quantity that measures the rate at which work is done or energy is transformed. mechanical advantage is a quantity that measures how much a machine multiplies force or distance. thank you for listening to my blog and good bye.

-Work; Power; && Mechanical Advantage!

Work is the transfer of energy to a body by the application of a force that causes the body to move in the direction of the force. Power is a quantity that measures the rate at which work is done or energy is transformed. Mechanical advantage is a quantity that measures how much a machine multiplies force or distance. No I didn't learn anything new today because we didn't take notes, so I don't have any questions, either.

work, power, and machanical advantage.

Worked is done only when force causes a change in the position or the motion of an object in the direction of the applied force. Worked is measured in joules (J). Power is the rate at which work is done, that is, how much work is done in a given amount of time. Power is measured in watts (W). Mechanical Advantage is defined as the ratio between the output force and the input force. Examples 1: Work- Liftying weights or lifting something heavy. Example 2: Power- Electricity and running. Example 3: Mechanical advantage- some machines help you lift or move heavy objects. I learned that Work, Power, and Mechanical Advantage all use force.

Work is done only when force causes a change in the position or the motion of an object in the direction. Mechanical advantage is defined as the ratio between the output force and the input force.Power is a quantity that measures the rate at which work is done or energy is transformed.
An example of work is a man lifting weights. An example of a mechanical advantage is using a ramp to load a motercyle of a fourwheeler. An example of power is like when you run you go faster.I didnt learn anything knew today.

Work power and chemical advantage

Work is known as the transfer of energy to a body by the application of a force that causes the body to move in the direction of the force. For example, as a father playing with his daughter by lifting her repeatedly in the air. The father is doing work by exerting a force on the girl. On the other hand power is a quantity that measures the rate at which work is done and energy is transformed. An example of power would be work divided by time, if you ran to your destination, it would take less time than walking does. Time and work influence power. Mechanical advantage is a quantity that measures how much a machine multiplies force or distance. Output force divided by input force influences mechanical advantage. So far I have no questions about the chapters curriculum.

Work, Power, and Mechanical Advantage.

Work is the transfer of energy to a body by the application of a force that causes the body to move in the direction of the force. Power is the quantity that measures the rate at which work is done or energy is transformed. An example of work would be trying to lift a car without a jack. An example of power is a measure of watts. An example of mechanical advantage is a ramp. I learned more about what each one is. I don't have any questions as of right now.

Chapter 12- work, power, and mechanical advantage!

Work is done when a force has cause a change in position or motion of an object. Power is the rate at which work is done and mechanical advantage is the ratio between the output forces and the input forces. Examples of work would be texting on your phone, power is the force you put into a work that is being done like how much the tracker speed should go. I have learned new few things for example the difference amount of work we can do, then if we get a tracker amount of how much it is easier to do it.

Work Power and Mechanical Advantage

I learned that work is the transfer of Energy to a body by the application of a force to the body to move in the direction of the force. Power is the quantity that measures the rate at which work is done or energy is transferred. Mechanical Advanage is how advantagous a machine is when reducing the amount of energy used to perform a task.

Work, power, and mechanical advantages

Work is done when a force causes a change in the position or motion of an object like when you push a rock. Power is the rate at which work is done like how long it takes to push the rock. Mechanical advantage is the numbers that describes how much the force or distance is multiplied by a machine like a tractor. I learned what the real meaning of work and power was and no i don't have any questions.

Chapter 12 Beginning

  Work is done when a force causes a change in the position or motion of an object. Work is like typing on your computer. Power- is the rate at which work is done. How much force you put on your keys when you type.  Machines help us by changing the distance over which a certain force is applied. Like tactors help us feed horses. I knew everything we went over, because we had already taken notes, and no i dont have any questions.

Work Power and Mechanical Advantage

Work is done when a force causes a change in the position or motion of an object. Power is the rate at which work is done. Mechanical Advantages tell how much a machine multiplies force or increases distance. We also learned about how simple machines work and make work easier for us. I find this chapter really interesting.
