(SI) UNIT OF WORK
NEWTON(N)
Newton (N) is NOT a unit of Work (energy) but of FORCE!!
WORK (Energy in) is Force Times distance moved in the direction of the force.
If you push a cart with 3 Newtons force for 5 meters you do 3 * 5 = 15 JOULES of work expending 15 Joules of energy
The JOULE is the SI unit of work and energy.
Newton is force
Joule is work
The SI (International System of Units) unit of work is the joule (J).
Work is defined as the transfer of energy that occurs when a force is applied to an object and the object is displaced in the direction of the force. It can be calculated by multiplying the magnitude of the force applied to an object by the distance it moves in the direction of the force.
To understand how the joule is defined and derived, we can start with the definitions of force and distance.
Force is usually defined in terms of Newton's second law of motion, which states that force (F) is equal to the mass (m) of an object multiplied by its acceleration (a): F = m * a. In SI units, the unit of force is the newton (N), which is defined as the force required to accelerate a one-kilogram mass by one meter per second squared (N = kg * m/s^2).
Distance is a measure of how far an object moves, typically measured in meters (m).
Now, to find the unit of work, we need to combine force and distance. Work (W) is calculated by multiplying force (F) by distance (d): W = F * d.
Substituting the SI units, we have: W (joules) = F (newtons) * d (meters).
Therefore, the unit of work in the SI system is the joule (J), which is equal to one newton-meter (N * m).
