From what I learned in physics class, the force you are speaking of is measured in Newtons.

Sorry you've had such rubbish answers. \n\nI'm usually quite good at this sort of thing, but I'm afraid I can't find any info on the origins of this phrase.\n\nI hope someone more knowledgeable answers you soon!

1.  To make null; invalidate.\n   2. To counteract the force or effectiveness of.

work = force * distance\n\nWork done is the product of the force exerted and the distance moved.\nno force, no work\nno distance, no work

This may actually have to do with Newtons laws of physics. This one would seem to be "Every action has an equal and opposite reaction"

Magnetic forces - magnetism - like force repel ( + to + or - to -)(repulsion) and opposite force attract (+ to -, - to +) (attraction).

Doing it frequently will certainly reduce the quantity and the force to some degree. But if you go a few weeks or more without it, look out!

The use of force by our federal government.\n\nNot just in attacking foreign countries but also in using force in the lives of individuals.\n\nFrom using force to dictate what an individual can or cannot put into their body to using force to take away the productivity earned by every individual.

A force at its most simplistic is a push or a pull. According to Newton's laws of motion, when something is at rest or travelling at constant velocity, there is NO force acting on it. \n\nNewton's second law states that Force = mass x acceleration which means that a force causes a _change_ in velocity (acceleration). So for continuing motion, there is only a force when there is acceleration.

A force is a push or pull on an object.\n\nNewton's second law states that a an applied force causes an object to accelerate.  It's one of the most if not the most powerful physics equations.  Force equals mass times acceleration.  F=ma.  So when an object falls the force of an object is equal to the mass of the object times the acceleration due to Earth's gravity (9.81 m/s/s or 9.81 meters per second per second or meters per second squared.)  All objects experience the same acceleration due to gravity.  The units for force are, oddly enough, called Newtons and one newton equals one kilogram times one meter per second squared.  One pound is 4.48 newtons. \n\nNow it's important to understand that newton's second law, F=ma, applies to net forces or unbalanced forces.  Just because an object is moving doesn't mean it's accelerating.  When you press the accelerator you car speeds up and the engine is exerting a net force on the car.  When your speed maxes out at 120 or however fast your car can go the force of the engine is ballanced against the forces against the car (friction from air, the road and the engine parts)  \n\nTake tug of war.  An set of even matched teams won't result in one team moving across the line.  The forces are balanced.  Add one more strong guy to one team and the weaker team will speed up from zero to slowly moving across the line.  \n\nAlso force is cumulative.  When you can't pick up a heavy box what do you do?  You get help.  One smurf can lift a pebble but the whole smurf village can lift a boulder.\n\nAlso acceration is velocity divided by time a velocity is different from speed in that velocity is a vector, it has magnitude (speed) and direction.  If you change directions you will accelerate.\n\nIf you're in a train with no windows and an increadibly smooth track you shouldn't be able to tell that you are moving if the train't velocity is constant, however if it speeds up, slows down or goes around a corner while going at a constant speed the velocity is changing.  In the first two cases because of a change in magnitude (speed) in the last case because of a change in direction and you experience a force that pushes or pulls you in a direction.\n\nWeight is the force due to gravity and can change due to the masses of the objects involved.  For example you may have a weight of 100 lbs on earth and a mass of 40 some kilograms but on the moon you weigh 1/6 as much but still have a mass of 40 kg.  On Earth you can convert between pounds (a measure of force) and kilograms (a measure of mass) because the acceleration due to Earth's gravity (9.81 meters per second squared) is the same and cancels out in the equation.

The second law of motion states that Force = mass * acceleration, or in other words, that force is directly proportional to acceleration.\n\nThe first law follows because it states that an object at rest or in uniform motion will stay that way unless a force acts upon it. Being at rest or in uniform motion means acceleration is zero. Anything times zero is zero, so no acceleration means no force, and vice-versa.

The fricional force between an object and a surface is dependent on two things,\nthe coefficient of friction between the two surfaces and the normal force exerted by the surface on the object.\nIf you increase either of these, the frictional force is increased, likewise, if you decrease (or make zero) any of these, the frictional force is less (or zero).
