Power is the amount of work a specific machine can do over a period of time. Work is the product of force and the distance an object travels as a result of that force.
A more powerful machine can effect changes in velocity of an object more rapidly than a less powerful machine.

What is the rate of the work being done known as?
Power. It is usually measured in Watts (or horse-power in vehicles).
If machine A performs work in twice as much time as machine B then machine B will use more what than machine A?
Machine B will use more power.
Watts are measured in?
voltage is measured in ohms which is represented by the omega sign.
A 700 watt gasoline engine and a 300 watt electric motor both do 3 joules of workwhich machine does work faster?
Power, measured in watts, is defined as the rate at which work is done. Therefore, the greater the power of an engine, the faster it does work. Therefore a 700 W engine always does work faster than a 300 W engine.
What unit of measure is used in potential energy formula?
potential energy = mass x gravity x height.Gravity is measured in units of acceleration.Specifically in the case of SI units:Energy is measured in joule.Mass is measured in kilograms.Gravity is measured in meters/second2, or the equivalent newton/kilogram. The numeric value is approximately 9.8 in either case.Height is measured in meters.
Which is measured by the power of a machine?
rate of doing work
How can a machine's efficiency be calculated?
You use the definition of "efficiency": you divide output power by input power. Both of these, of course, need to be measured or calculated.
Why is horsepower used in describing the power output of a motor or engine?
Simply that horses were used before motors and engines. The standard used to measure how efficient a machine was therefore a horse. So a 2 HP (Horse Power) motor could do the work of 2 horses.CommentThe output power of a machine is only measured in horsepower in the US; elsewhere, it's measured in watts.
What is power measured in?
Power is measured in watts.
Machine cycle time can be measured in?
It can Be measured with a meters or the stopwatch or amything.
Is the power of engines measured in hydraulic power or horsepower?
Engine power is measured in horsepower.
How is power measured in an engine?
Power is measured in both torque and horsepower.
Machine cycle time measured in?
NS
What is force measured with?
im pretty sure that force is measured with a scale/ weighing machine
Power is measured in j per what?
Power is measured in Joules per Kilowatt.
The power pf light bulbs in Measured in?
The power of light bulbs is measured in
The power of lightbubs is measured in what?
it is measured in watts
