Newtons 3 laws of motion say:\n1) An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.\n2)F=MA or force = mass times acceleration. It describes how an unbalanced force acts in the first law. THIS IS THE MOST IMPORTANT DISCOVERY IN ALL THE HISTORY OF SCIENCE!!!!!\n3) For every action, there is an equal and opposite reaction.\n\nNewton also discovered that gravity is a force of attraction between two masses that is equal to the product of the two masses times the gravitational constant divided by the square of the distance between them. Or F=GMm/R^2.\n\nThe combination of all of the above explains all orbits, rocket propulsion, life the universe and everything!\n\n\nThen Einstein comes along and messes it all up. He says that there is a small error in Newton's laws that depends on the speed. For stuff going really fast, Newtons laws are just totally wrong. Gravity isn't even a force at all, it is a curvature in space time.\n\nBut for every day applications, like designing a 747 or computing the path of an artillery shell or a zillion other things, Newtons laws are still used as is because the errors are vanishingly small under normal conditions.

In physics, a force is anything that causes a body with mass to accelerate. The net (or resultant) force is the sum of all the different forces acting on a body.\n\nForce is a vector quantity defined as the rate of change of momentum induced by the force, and therefore has a direction associated. The SI unit for force is the newton.

I think you mean NEWTON's laws of motion, named for the preeminent scientist Isaac Newton.\n\n-Unless acted upon by an unbalanced force, an object will maintain a constant velocity.\n\n-The rate of change of momentum of a body is equal to the resultant force acting on the body and is in the same direction.\n\n-All forces occur in pairs, and these two forces are equal in magnitude and opposite in direction.

begin our explanation of how Newton changed our understanding of the Universe by enumerating his Three Laws of Motion. \n\nNewton's First Law of Motion:\nI. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.  \n\nThis we recognize as essentially Galileo's concept of inertia, and this is often termed simply the "Law of Inertia". \n\nNewton's Second Law of Motion:\nII. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.  \n\nThis is the most powerful of Newton's three Laws, because it allows quantitative calculations of dynamics: how do velocities change when forces are applied. Notice the fundamental difference between Newton's 2nd Law and the dynamics of Aristotle: according to Newton, a force causes only a change in velocity (an acceleration); it does not maintain the velocity as Aristotle held. \n\nThis is sometimes summarized by saying that under Newton, F = ma, but under Aristotle F = mv, where v is the velocity. Thus, according to Aristotle there is only a velocity if there is a force, but according to Newton an object with a certain velocity maintains that velocity unless a force acts on it to cause an acceleration (that is, a change in the velocity). As we have noted earlier in conjunction with the discussion of Galileo, Aristotle's view seems to be more in accord with common sense, but that is because of a failure to appreciate the role played by frictional forces. Once account is taken of all forces acting in a given situation it is the dynamics of Galileo and Newton, not of Aristotle, that are found to be in accord with the observations. \n\nNewton's Third Law of Motion:\nIII. For every action there is an equal and opposite reaction.  \n\nThis law is exemplified by what happens if we step off a boat onto the bank of a lake: as we move in the direction of the shore, the boat tends to move in the opposite direction (leaving us facedown in the water, if we aren't careful!).

The answer is C. Although B seems to be a possible answer at first, there could still be an n-number of forces acting on the object such that the sum of all the force vectors is zero, thus making C the more complete answer. One of Newton's laws says that F=m*a (force on an object equals its mass times its acceleration), or a force of 1 Newton on a 1kg object will make it accelerate at a rate of 1m/s^2 in the same direction of the force.

Newton's first law: The force of the car, an unbalanced force, pushes the car forward and the car keeps moving until another unbalanced force stops it. \n\nNewton's second law: The car has mass and accelerates, so therefore it has force. Also, the car goes in the direction in which the force is pushing it.\n\nNewton's third law: The car pushes back on the track and the force of it pushing back sends it forward. This proves that for every action there is an equal but opposite reaction.

E=Mc^2 is not newtons 2nd law of motion\n\nEnergy = mass in kg * the speed of light squared which is in m/s\nThat is the full equation,it is by no means a proof but it is the equation\nNewtons 2nd law of motion is mass * acceleration,acceleration has units of m/s^2\n\nLight does not accelerate\n\nE= mc^2 is used to find how much erergy is required to create new mass,it is used a lot in particle physics

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.

This is really simple stuff. Newtons is force, seconds is time, meters is length, and meters per second is length per time, or velocity.

Newton's laws of motion.\nConservation of engery.\nConservation of momentum.
768941
Newton's 2nd Law is about conservation of momentum\n\nAn example would be when the space shuttle is decreasing its speed in order to land on the comet\n\nNewton's 3rd Law\n\nWhen the crew were drilling into the comet, the drill was exerting a force into the rock and ice. The comet itself was exerting a force equal to the drill. That is why it was shaking.\n\nAnother example would be when the space shuttle was taking off from the comet.

Newton's Laws of Motion describe only the motion of a body as a whole and are valid only for motions relative to a reference frame. \nFirst law - An object at rest tends to stay in rest and an object in motion tends to stay in motion in a straight line at constant speed unless acted upon by an external, unbalanced force - like those big propellers. \nSecond law - The rate of change of momentum of a body is proportional to the resultant force acting on the body and is in the same direction. Which is why a really big submarine needs really big propellers to go.\nThird law - To every action (force applied) there is an equal but opposite reaction (equal force applied in the opposite direction).   So if the propeller pushes against the water one way, the propeller and the ship it is attached to move the other way.

im pretty sure itz derived from newtons laws. his F=ma.

Third law\n    To every action (force applied) there is an equal and opposite reaction (equal force applied in the opposite direction).\n    Another way of stating Newton's third law, an interaction between two objects, is that, if object A exerts a force on object B, object B will exert the same magnitude force on A, but in the opposite direction.

both are the same thing.\n\nHooke's Law for Springs. F = kx\n\nThat is linear and F is directly proportional to x with a proportionality constant of k.
