What is the definition of joule?
A joule is a unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
What is another way to write a newton?
A newton can be expressed in terms of base SI units as kg·m/s², which represents the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. Additionally, it can be represented as a derived unit involving the joule and the meter, since one joule is equal to one newton-meter.
How do you write the quantity 40W in terms of newtons?
Watt is a unit of power, newton is a unit of force. 1 joule (unit of enrgy) is equal to one newton-meter, and one watt (unit of power) is equal to one joule/second, so 1 W = 1 Nm/s.
Is joules equal to power?
It is the unit used to measure energy or work. The definition is that one joule is equal to the energy used to accelerate a body with a mass of one kilogram, using one newton of force, over a distance of one meter
Does one meter equal ten centimeters?
No, one meter dies not equal ten centimeters, one meter equals one hundred centimeters. The name for a tenth of a meter is a decimeter.
