A joule is the SI unit of energy, representing the amount of work done when a force of one newton is applied over a meter, while an erg is a much smaller unit, used in the CGS system, equal to 10^-7 joules. Difference Between Joule and Erg ...
What is the difference between cenroid and center of gravity? Explain how does the rotation of the Earth makes a body weigh more at the poles than at the equator. What is the difference between a gibbous moon and a crescent moon?
Besides, the calculation of work is an easy process that you should find convenient to grasp. Suppose, you apply a force ‘f’ (in Newton or N) on an object and it has a displacement of ‘d’ (in meters or m), then work – w = Fd The SIunit of workis the joule (or J) whi...
Know about Nuclear Fission and Fusion at BYJU'S. Learn the difference between nuclear fission and fusion in detail.
What is the difference between the meaning of measurement and the value of measurement in physics? Determine the units of Planck's constant. What other physical quantity has the same units? Define Newton unit of measure What is the difference between the units of Tesla...
as opposed to horsepower. The unit newton meter is properly denoted N-m and is used to measure torque in system international (SI). The SI unit for energy or work is the joule. It is dimensionally equivalent to a force of one newton acting over a distance of one meter, but it is not...
1 relationship with other units. The standard definition is one joule per second, but in mechanical terms it is also equal to the torque in newton metres per radian times the speed in radians per second. Using “rpm” takes away this coherency and consistency and gives the watt an aura of...
Kilojoules are the SI unit to measure energy. 1000 joules are equivalent to a 1 kilojoule. Joule has different definitions based on the form of energy that we measure with it. We can define it as the energy needed to apply a 1 force of Newton to move 1 m distance. ...
What is the difference between Temperature and Thermal Energy? • Thermal energy is not a directly measurable quantity whereas temperature is a measurable quantity. • The temperature of an object can take negative values depending on the unit system used to measure the temperature, but the ther...
Joule is a unit of energy, while watt is a unit of power. Difference Between Joule and Watt Table of Contents ADVERTISEMENTKey Differences Joule represents energy, and it is the amount of work done when a force of one newton moves an object one meter. Watt, on the other hand, signifies...
