79947
The unit of force is the Newton (N).\n\n1 newton is defined as the force needed to accelerate a 1kg object at 1m/s*2.(from Newton's 2nd Law of Motion: F = ma)   \n\nSometimes it is given in its base units as kgm/s*2

The theoretical physics equation E = mc2 states a relationship between energy (E), in whatever form, and mass (m). In this formula, c², the square of the speed of light in vacuum, is the conversion factor required to formally convert from units of mass to units of energy, i.e. the energy per unit mass. In unit specific terms, E (Joules) = M (kilograms) · (299792458 m/s) 2.

Kinesiology II\n Physics of Motion\nI.  Force \nA.  Definition\n1.  Force = mass * acceleration\n2.  Mass is a fundamental dimension, units g, kg\n3.  Acceleration is change in velocity, units m/sec/sec or m/s2\n4.  “Weight” is a force, units pounds or Newtons\n- Pounds = mass * acceleration of gravity\n- Why your weight, but not your mass, is different on the moon\n- Gravity on Earth = 9.8 m/sec2 \n5.  Example:  A person with a mass of 70 kg weighs:\n                        70*9.8 = 686 kg*m/sec2 or 686 N\n \nB.  Aspects\n1.  Force has a point of application or origin\nExample:  location where muscle attaches to bone\n2.  Force has a line of application\nFollows the tendon\n3.  A rotational force is called torque\n4.  Force has direction\nCan be indicated in two (x,y) or three (x,y,z) dimensional space\n5.  Force has magnitude\nMagnitude is measured in Newtons\n \nII.  Rotational Force \n1.  Force (mass*acceleration) may cause rotation about an axis\n2.  Moment of force (=Torque) is equal to the force times the lever arm – the perpendicular, straight line distance between the axis of rotation and the force\n3.  Moment of force (torque) = force* perpendicular distance \nUnits:  N*m\n4.  Sign convention:  \nClockwise moment = negative\nCounterclockwise moment = positive\n \nIII.  Levers – Location of effort force, load or resistance force, and rotational axis\nA.  Three types of levers\n1.  First class\n2.  Second class\n3.  Third class\n4.  Differences between the three have to do with the relative locations of the effort, load, and the axis of rotation\n \nB.  First Class Lever\n1.  “EOR”\nO = axis or pivot point\nE = effort force (as applied by muscle/tendon)\nR = resistance (load) force (outside force such as barbell)\n2.  The effort force and the load force are located on opposite sides of the axis of rotation\n3.  Example:  seesaw\n4.  Anatomical example:  Triceps muscle – elbow extensor\nInsertion:  Olecranon process of ulna\n5.  First class levers are rare in human body\n \nC.  Second Class Lever\n1.  “ORE”\n2.  The resistance (load) force and the effort force are on the same side of the axis of rotation\n3.  The effort lever arm is GREATER than the resistance lever arm\n4.  Example:  wheel barrow\n5.  Anatomical example:  brachioradialis – elbow flexor\nInsertion:  Styloid process of radius (distal – past the center of mass)\n6.  Second class levers are rare in the human body\n \nD.  Third Class Lever\n1.  “OER”\n2.  Effort and resistance (load) forces are on the same side of the axis of rotation\n3.  The effort lever arm is SMALLER than the resistance lever arm\n4.  Anatomical example:  Biceps brachii – elbow flexor\nInsertion:  Tuberosity of radius (proximal)\n5.  Anatomical example 2:  Quadriceps group – knee extensors\nInsertion:  Patella, tibia \n6.  Third class levers are common in the human body\n \nIV.  Mechanical Advantage\n     A.  Mechanical Advantage defined as:\nEffort Lever Arm/Resistance Lever Arm\n1.  A second class lever will always have a mechanical advantage greater than one because the effort lever arm is always GREATER than the resistance lever arm\n2.  A third class lever will always have a mechanical advantage less than one because the effort lever arm is always LESS than the resistance lever arm\n3.  A first class lever can have a mechanical advantage less than, equal to, OR greater than one, depending on the locations of the effort force and resistance force versus the axis of rotation\n \nB.  Mechanical Advantage VS. Speed\n1.  The mechanical advantage of a third class lever – common in the body – is poor – always less than one\n2.  However, the SPEED of rotation created by a third class lever is high\n \n\n3.  Because the origin of the resistance force is located farther from the axis than the origin of the effort force, it must travel a greater distance in the same time\n4.  Greater distance per unit time = greater speed\n5.  Good for throwing objects, kic

Force is some thing that alters the state of things. According to Newton's second law of motion force produce acceleration in a mass object - either by putting it to motion from a state of rest or from a slower speed, or by slowing things down. In either way F= ma or F = -ma (slowing down).Where F is force, 'm' is unit mass, and 'a' stands for acceleration, and '-a' for deceleration.\nBasically it is about change - change in inertia.\n\nWhereas momentum M= mv is not about change in inertia but about inertia itself. You see every thing in universe if composed of mass and energy. Energy  of a stationary object of of 1 kg is not same as that of an object of same mass moving with certain speed.\nSo momentum is a product of mass and velocity of the object.\nAnd force in lay man's term is a means of transferring energy from on object to an other.

The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length. It is approximately equal to the mean distance between Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles).

Yeah, force is just energy applied on a particle. Force per time is power.

AREA\n\nPressure (symbol: p) is the force per unit area acting on a surface in a direction perpendicular to that surface. Mathematically:    P=F/A\nwhere:\np is the pressure \nF is the normal force \nA is the area.

Weight is a force, but when something is weighed you actually measure it's mass assuming you are in an environment in which the force of gravity is constant (i.e., you're at a fixed location <radius from the center> on a planet or massive planetary mass).\n\nof course, one's mass can be approximated by W=mg at fixed radii from such planetary masses (like the earth, a massive asteroid, a superdense star, whatever...) if the force of gravity, g, is known at that radius.\n\nThere are 2 possible variables here - mass and the force of gravity.  Which one do you know?  usually an approximation for g is given.  Which one do you measure, then...that would be mass.

E=MC squared. \nE is energy.\nM is mass(weight).\nC is the speed of light.\n\nForce, on the other hand, is mass times speed.
