The work energy translates in your example to kinetic energy in the object. Power is work per time. Consider the work, kinetic energy, object velocity, and power input for 1 N in two cases, applied for 1 s to move 1 kg by 1 m and applied for 100 s to move 100 kg by 1 m. w1 = (1)(1) = 1 J. EK1 = 1 J. v21 = 2 (m/s)2.
The energy expenditure in doing so will still be equal to one joule. Note, however, in this case the mass is 100 times as great as the previously stated 1 kg, yet the distance moved is one one-hundredth of that previously stated distance of 1 m. Everything is in proportion. The energy expenditure, one joule, or one watt, is the same.
PV = nRT P V = n R T. or, expressing pressure as a function of volume, P(V) = nRT V P (V) = n R T V. meaning, for an ideal gas, the pressure varies inversely with volume if the temperature is constant (an isothermal process). It can not vary directly (linearly) with volume. But the problem statement does say " somehow " the helium is made to to ...
To prove how volts is related to energy transfer and charge you can do: E = VIt. V = E/It. V = J/Cs -1 x s. You can cancel out the seconds, leaving: J/C. Joules per coulomb is equal to volts. This is how we've been taught, but I don't understand why for current (Cs) it is to the power of -1. Please could someone explain to me why Cs is to the ...
The volt is the electric potential difference that yields one joule of energy difference per Coulomb of charge. So multiplying by an Ampere (one Coulomb per second) gives one joule per second. So, that's how you can trust that a battery that says '2 Volts' can deliver up to IV I V in power.
If 1 watt is equal to 1 joule per second, then 1 MW is equal to 1,000,000 joules per second or 1,000,000 joules/second. What is the word for unit of measurement of energy? A Joule … the ...
As you already said One Joule is 1 Joule is 1 newton exerted through a distance of one meter. Joules measure how much energy you need to give to the system to move it from point A to point B. And, as you rightly said it is measured by W=F*d. So 490J 490 J is 490N 490 N over 1 metre as 490 ∗ 1 = 490 490 ∗ 1 = 490 also it is 1N 1 N over 490 ...
A joule = Nm therefore one joule = 1/m Newtons or 1 N for I meter or 2 N for 1/2 meter, or 5 N for 1/5 meters or 1/2 N for 2 meters.
1 Joule is equal to 10,000,000 Ergs. This conversion is based on the definition that 1 Joule is equivalent to one Newton meter, and 1 Erg is equivalent to one dyne centimeter. Therefore, the ...
The units for torque, as you stated, are Newton-meters. Although this is algebraically the same units as Joules, Joules are generally not appropriate units for torque. Why not? The simple answer is because. W = F ⋅d W = F → ⋅ d →. where W W is the work done, F F → is the force, d d → is the displacement, and ⋅ ⋅ indicates the ...
