How does power vary with spent time in doing work?
Power is the rate at which work is done, so if the time spent doing work increases while the amount of work stays the same, the power output decreases. Conversely, if the time spent doing work decreases while the amount of work remains constant, power output increases. Power is directly proportional to work done and inversely proportional to the time taken to do that work.
What formula relates work and power?
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
How do you calculate work with power and time?
Work can be calculated by multiplying power by time. The formula is: Work = power × time. This equation is derived from the definition of power, which is the rate at which work is done over time.
Why can power and velocity each be considered rates?
Its to do with constant values, the rate of acceleration refers to a constant change of velocity over time, so an acceleration of 10 (m/s)/s is a constant increase of velocity per unit time ( increase of 10 metres per second, every second )Velocity is a constant increase in distance, per unit time (metres per second)
How does speed affect Power?
Speed is directly related to power. As speed increases, power also increases. And as speed decreases, power also decreases.
How does power vary with spent time in doing work?

Conversely, if the time spent doing work decreases while the amount of work remains constant, power output increases. Power is directly proportional to work done and inversely proportional to the time taken to do that work.
What happens to power as the time required to do work Does power increase or decrease?
Power is the rate at which work is done. If the time required to do work decreases, the power increases because the same amount of work is done in a shorter period of time. Conversely, if the time increases, power decreases because the work is done at a slower rate.
How can work affect power?
'Power' is the rate of doing work.
Does power equal work over time?
Power = work/time So time = power/work and work = power x time.
The formula work and time is used to calculate what?
Power = Work/Time Time = Work/Power Work = Power * Time See related links for a power calculator. Insert work and time to calculate power.
What formula relates work and power?
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.

How are power work and time related?
Power, work, and time are related through the equation Power = Work/Time. Power measures the rate at which work is done, while work is the transfer of energy that results in a change in the state of a system. Time is the duration over which work is done, influencing the power required to perform the work efficiently.
What equals work divided by time?
Work divided by time is power.
Is power transformer is constant current device?
No, it has to be an alternating current in order to work
How does speed affect Power?
Speed is directly related to power. As speed increases, power also increases. And as speed decreases, power also decreases.
