Which is the unit of force?

In physics, the force you apply to move or stop something is measured in Newtons. A Newton is the amount of force that gives a mass of 1 kilogram an acceleration of 1 metre per second squared, according to F = ma. That connection to acceleration is what makes Newton the natural unit for force. Joules are units of energy (they’re related to force and distance, since energy can be written as force times distance). Metres measure length or distance. Pascals are units of pressure (force per area, N/m^2). So the unit for force is Newtons.
