What else can I help you with?
What does the power of a machine tell you?
How fast work happens or how quickly energy is transferred.
How does the scientific use of the word efficiency differ from the everyday use of the word?
Energy is scientifically defined as the ability to do work, and power as the rate at which work is done, or the rate at which work is expended.
Why when you push an object across a desk the work done is not equal to the change in gravitational potential energy?
In this case, you are not doing work against the force of gravity, but against the force of friction.
How much power is used when 600J of work are done in 10s?
60 W
Which forms of energy can do work?
The forms of energy that do work is kinetic energy.
What different between power and energy?
Power is the rate of doing work or delivering energy whereas energy is the capacity for doing work.
What is the rate of doing work of using energy?
(physics) the rate of doing work; measured in watts (= joules/second) - See more at: http://www.chacha.com/question/what-is-the-rate-of-doing-work-or-using-energy-(58%26%2345%3B19)#sthash.l6xRuIk4.dpuf
How can you storage of electrical power?
You cannot store power any more than you can store velocity, because it is simply a 'rate' -the rate of doing work. In order to do work you can store potential energy in, for example, the form of water held behind a dam. When the water is allowed to pass through a turbine, that turbine does work by converting this energy into electrical energy.
The power of a machine measuer what its rate of doing work the force it produces its strength the work it does?
"Power" is the rate of work, or of energy transfer.
What is the rate of doing work or using moving energy?
The rate of doing work or using moving energy is known as power. It is measured in watts and represents how quickly energy is transferred or work is done. Power is calculated by dividing the work done by the time taken to do the work.
Is the time rate of doing work.?
Power is the rate at which work is done or energy is transferred. It is measured in watts (W) or horsepower (hp).
Doing work at a faster rate requires?
it requieres speed,strenth,and energy
What is the rate of doing work or using energy?
(physics) the rate of doing work; measured in watts (= joules/second) - See more at: http://www.chacha.com/question/what-is-the-rate-of-doing-work-or-using-energy-(58%26%2345%3B19)#sthash.l6xRuIk4.dpuf
When a muscle contracts it performs work It does this by?
When a muscle contracts, it performs work. It does this byA)converting chemical energy to mechanical energy.B)converting mechanical energy into heat energy.C)converting mass into energy.D)creating energy.
Is defined as the rate at which work is done?
The term that represents the rate at which work is done is the watt. It is defined as 1 joule per second.
How are work energy and power related?
Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time
The rate (speed) of doing work is a measure of?
The rate of doing work is a measure of how quickly energy is transferred or converted. It is calculated as the amount of work done divided by the time taken to do the work. The unit of power, watts, is commonly used to express this measurement.
