How do you calculate work from joules?
One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
- Work can be calculated with the equation: Work = Force × Distance.
- The SI unit for work is the joule (J), or Newton • meter (N • m).
How do you find seconds from joules and watts?
Power is equal to the energy in joules divided by the time in seconds. For example, find watts of power for 250 joules of energy over 40 seconds.
How do you find joules per second?
Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s).
How do you calculate work time?
Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.
How do you calculate watts per second?
The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.
What is rate of work done?
The SI unit of work done is joule. Now, the rate of work done means the amount of work done per unit time. Now, power can be defined as the amount of energy Transferred per unit time. Energy transferred is the same as the work done on the object.
How do you do rate of work problems?
To solve a work word problem, multiply the hourly rate of the two people working together by the time spent working to get the total amount of time spent on the job. Knowledge of solving systems of equations is necessary to solve these types of problems.
How do you calculate watts per minute?
