That which causes acceleration.

BUT THAT'S CIRCULAR!!! WTF

how? acceleration is a change in velocity, force causes that change

A force is a current of momentum, it's momentum flowing from body to body. When a body gives a certain number of "Barnetts" of momentum (there is no name for the unit of momentum) per second, that's a force.

Since momentum is conserved, the other body gives an equal number of Barnetts per second back to the first. This is Newton's third law.

The notion of force is exactly analogous to the notion of "current", except the conserved quantitiy is momentum, which is a vector, while current is for charge, which is a scalar. In the old fasioned (and incorrect in precise details) Kaluza Klein theory, charge is just another component of momentum, in the 5th dimension, and "force" and "current" are unified.

the idea that something is causing something else to happen, by means of pushing/exerting.
for example if gravity is not a force and is infact the opposite, then it would be and perhaps is existence approaching a state of greater stillness. so for that reason gravity is not a force. its just what happens

FUCKING MAGNETS

You could also think of a force as a change in energy, if you apply a force over a distance it will change the kinetic or potential energy of an object.

How many Barnetts are you guys channeling right now? I can't work it out! Help me with the calculation so we can join forces and channel our Barnetts together!

FUCK OFF JACOB

OK, OK, I SEE WHAT'S HAPPENING HERE
YOU'RE FACE TO FACE WITH GREATNESS, AND IT'S STRANGE
YOU DON'T EVEN KNOW HOW YOU FEEL..IT'S ADORABLE!
WELL, IT'S NICE TO SEE THAT BRAINLETS NEVER CHANGE
