-- Magnitude of the force (or force as a function of time)
-- Distance through which it acted (or position as a function of time)
-- Duration of the time during which it persisted
Work is the product of (force) x (total distance).
Power is (work) divided by (duration of the time).
If the force and distance are functions of time, then I'm not sure how to do it right now,
but I know there's an integral in there somewhere, and I'm not happy about that.
You would need to know other physical properties to be able to calculate the length. As you would need to know certain properties to be able to calculate the volume, for instance.
You need to know both of them in order to calculate speed.
The best strategy in that situation would be to use what you do know.
In that case, it would be good to know WHAT is given. If NOTHING is given, you really can't calculate.
Power = (work) divided by (time) If you don't know the amount of work, you can calculate it. Work = (force) times (distance).
If you know the power you do not need to calculate it by anything. And if you don't, the answer will depend on what measure you do know!
Impossible to know. You need to know both the voltage and current draw to calculate power (watts). Power in watts = Volts X Amps
you must know time to determine both work and power

Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
You need to know both of them in order to calculate speed.
we can calculate power consumption of motor by multiplying voltage and current which motor is take.AnswerYou need to know its rated power (i.e. its output power) and its full-load efficiency, from which you can calculate its input power.
You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth. But the log, itself, is not something you can calculate.You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth.

Volts measure electrical potential, while watts measure power. They are different units that cannot be converted directly. In order to calculate voltage, you would need to know the current (amperes) in addition to the power (watts).

Well, the first step is to learn joules and you'll be set!
It easy.We know p=vi.So just put the value in the equation.
