What is the unit for joule per second?
watt
The SI unit of power is the watt [symbol W] which is a rate of 1 joule per second.
What is NM 1s2 equal to?
It is dimensionally equivalent to the momentum unit kilogram-metre per second (kg⋅m/s). One newton-second corresponds to a one-newton force applied for one second….
| Newton-second | |
|---|---|
| In SI base units: | kg⋅m/s |
Is joule a SI unit?
The SI unit for work and energy commonly used in drawing is the joule (J), which is equivalent to a force of one newton exerted through a distance of one meter (m).
What is the unit of 1 nm?
One newton-metre is the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long. The newton-metre (also newton metre or newton meter; symbol N⋅m or N m) is a unit of torque (also called moment) in the SI system.
What unit is kg * m s?
A newton is defined as 1 kg⋅m/s2, which is the force which gives a mass of 1 kilogram an acceleration of 1 metre per second, per second.
How much electricity does a 100 watt lamp consume?
Complete step by step answer: And we are to calculate the energy consumed by this bulb in two (2) hours. We know that electrical energy is usually measured in units of kilowatt-hours, which is equal to about 3.6 megajoules. Therefore, the correct answer is 0.2 kilowatt-hours.
What is the formula of one joule?
In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
Which is another form of 1 Joule?
1 Joule is equivalent to one Newton-meter (N-m) where 1 J is the amount of work done by a newton of force to a distance of 1 meter.
What is the smallest unit of power?
Milliwatt
The smallest unit of power is Milliwatt.
Is the joule second a unit of angular momentum?
The joule-second is a unit of action or of angular momentum. The joule-second also appears in quantum mechanics within the definition of Planck’s constant. Angular momentum is the product of an object’s moment of inertia, in units of kg⋅m 2 and its angular velocity in units of rad⋅s −1.
Is the joule second the same as the joules per second?
From Wikipedia, the free encyclopedia Not to be confused with Joules per second. The joule-second (symbol J⋅s or J s) is the product of an SI derived unit, the joule (J), and an SI base unit, the second (s). The joule-second is a unit of action or of angular momentum.
Which is the SI unit of momentum mass or velocity?
SI Unit of Momentum As mentioned above, the units of momentum will be the product of the units of mass and velocity. Mass is measured in kg and velocity in ms -1, therefore, the SI unit of momentum will be kgm/s (-1).
How is angular momentum related to angular velocity?
Angular momentum is the product of an object’s moment of inertia, in units of kg⋅m 2 and its angular velocity in units of rad⋅s −1. This product of moment of inertia and angular velocity yields kg⋅m 2 ⋅s −1 or the joule-second.
