What is the conversion from joules of energy to watts of energy?
There is no conversion, as joules measures energy and watts measures power -two different quantities!
If it takes 10 seconds and 100 N of force to move an object 10 meters What is your power?
Power (the rate of energy use) is calculated as the product of the energy exerted (work) divided by the time over which the energy is released. P = W/t To solve the example, multiply the force in Newtons by the displacement in meters to find the work in joules, then divide by the time to find the power required, in watts (joules/second, or kg-m2/sec3) 100 N x 10m = 1000 joules divided by 10 seconds = 100 watts
What is energy measured by?
Energy is measured in Joules in the SI system. Thermal energy can be measured in calories (1 calorie = 4.2 Joules) or BTU. In traditional units, energy is in ft.lbforce! energy is measured in calories and use to be measured in joules
What is the equation for energy transferred by an electrical appliance?
Energy = power x time. If power is in watts, and time in seconds, energy will be in joules.
What thermal energy is supplied by the heater in 10swhen the power is 1440w?
Since power is defined as energy/time, if you solve for energy, you get:energy = power x timeIf the time is in seconds and the power in watts, the energy is in joules.
The ability to cause change?
energy is the ability to cause change or do work
What is the speed at which energy is transfered?
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts

The rate at which energy is transfered is called?
That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power".

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
What does power times time equal?
Power is defined as energy per unit time or Joules per second if you use SI units. This means that multiplying power by time leaves Joules, or energy. Power times time = energy
How many watts are 4680000000joules?
Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.
Is the length of time an electrical load is on proportional to power or energy?
Power (watts) is amperes times voltage, or joules per second. Energy is joules, or watt-seconds. The length of time an electrical load is on is proportional to energy, not power.
How much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
Difference between strength and power?
Strength is the amount of force your muscles can produce.Strength is often measured by how much weight you can lift or how much resistance you can overcome. people with good strength can perform daily tasks efficiently- that is, with the least amount of effort.Power is the ability to use strength quickly. it involves both strength and speed. People with good power might have the ability to put the shot, throw the discus, jump high, play football, and speed swimSo the difference is that Strength is the amount of force your muscles can produce, and Power is the ability to use strength quickly.
