231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.

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.

Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.

There are 3600 seconds in one hour. Therefore, 100 yards per second is equal to 100 x 3600 = 360000 yards per hour. There are 1760 yards in one mile. Therefore, 360000 yards per hour is equal to 360000/1760 = 204.54 recurring (that is, 204.545454...) miles per hour.

You can't convert them directly, because they measure different things. The unit for energy is the Joule. Power means how fast energy is transferred; it is measured in Joules/second, also called Watts.

How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.

The kinetic energy of a cricket ball depends on its mass and velocity. For example, a cricket ball weighing 160 grams and traveling at a speed of 140 km/h (38.89 m/s) would have a kinetic energy of about 110 joules.

Needs conversion. 2 m/s (1609 meters/1 mile) = 3218 meters per second ( fast!! ) Kinetic Energy = 1/2(mass)(velocity in meters per second)^2 KE = 1/2(1 kg)(3218 m/s)^2 = 5177762 Joules ( 5.2 X 10^6 Joules ) --------------------------------------------------

He should eat banana and/or honey

maybe your strategies dont work for your team or you run out of energy too fast. it depends from person person

No specific time. BTU is the quantity of energy, BTU/hour is the measure of how fast the energy is transferred. Just like I could hand you one dollar bill, or i could give you a penny a minute for 100 minutes. You would end up with the same amount of money (or energy,BTU) the only difference is how fast you got it.

it depends to the kind of energy
