how is momentum directly related to the force produced by a moving object?

If by force you are refering to the kinetic energy of a moving object, then the equation is as follows: kinetic energy = one half momentum squared/mass.  Momentum of course can be calculated by mass times velocity.

Imagine someone hit you with a ball. How much would it hurt? Depends doesn't it. If they threw a nerf ball at you really fast you would hardly feel it. If they threw a baseball at you at a much slower speed the impact would be much greater. The nerf ball has less mass than the baseball but was thrown at a greater velocity. Velocity is speed in a particular direction. How much you feel it in this case is due to the ball's momentum. Since momentum depends on both the mass and velocity of a moving object we express momentum in the following formula: Momentum equals mass times velocity or mom = m x v. Impetus is a less specific word. It is defined as the quality described by the mass of an object and its motion. Impetus is less specific (less to the point, vague) than momentum because it depends upon motion rather than velocity.

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.

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.

I believe so.  The formula for momentum is mass * velocity.  If your mass is zero or velocity is zero, this will make your kinetic energy zero as well (formula for kinetic energy is 1/2 * Mass * velocity squared).  Momentum and kinetic energy both deal with movement.

Eric L is right. Kinetic energy is proportional to speed SQUARED. It is momentum that is linearly proportional to speed.

Momentum is the direct result of the following Newtonian Law of Inertia\nAny object in motion remains in motion and any object at rest remains at rest (unless a net force acts upon the object)\nMomentum (p) is the mass (m) of the object times its velocity (v).\np = mv\n\nForce (F) and Newtons Second Law can be derive from a change in momentum.  That is (t is time)\nF = delta p/delta t \nF = delta (m*v) / dt\nwe usually say m is constant so\nF = m * v/dt\nF =  ma    (a is acceleration or a change in v/time)\n\nNewtons third law is also based on momentum.  "For every action there is an equal, yet opposite, reaction."\n\nSo...  When a gun is fired what we see is the bullet propelled forward and the gun (and gun holder) propelled back.  Both received the same Force but because the gun and person holding it are much more massive than the bullet, the bullet will travel much faster. \ne.g F1 is the force on the bullet which is the same as the force on the person F2\nF1 = F2\ndelta p1/dt = delta p2/dt\nm1v1/dt = m2v2/dt\nm1v1 =m2v2\nImagine the bullet is 1 gram and a 180 lbs (~8182 grams) person shot the bullet...  The avg v on the kick back will be about 1/8182 of the v of the bullet...  Lucky for the shooter.

Lets say your mass(not weight) is 10kg. and you are running at the speed of 10m in 1 sec(10m/s).\nSo your momentum is mass x velocity = 10kg x 10 m/s = 100kgm/s\nSo momentum of a body is the product of its mass and velocity.\n(use this formula to calculate the momentum of a body)\n\n\nForce is that physical cause that changes the state of rest or of motion of a body.\nF= ma; F is force, m is mass of the body on which the force is applied, and 'a' is the accalaration of the body with mass m.\nYou use this formula to calculate the force on a body, all you need to do to find it out is multiply the accelaration and the mass of the body.

Momentum is the tendency of an object in motion to stay in motion. The speed of light is an actual speed.

well, if an object is moving, there must be some physical force applied to it - magnetic field, static electicity, pull from a sting, air pressure from a fan.

This depends on whether you choose to consider the ball as a whole or as a conglomeration of individual particles.\n\nThe ball as a whole should have no momentum, since it has zero velocity. However, it may have potential energy if it is some height off the ground.\n\nThe particles in the ball have momentum because they are moving. Likewise, they also have kinetic energy, and potential energy from their height and the electromagnetic and nuclear forces.

The momentum of an object is defined as:\n\nMomentum = Mass * Velocity (speed)\n\nor:\n\np = m * v\n\nTherefore, an elephant, which is significantly more massive, would have a greater momentum.\n\nHere's a fun head-game: think of momentum as a measure of how much effort is required to stop a moving body. Now imagine that an elephant and a mouse are both running toward you at the same speed. Which one will be harder to stop?\n\nThe mouse will simply bump into you, and will probably spend the rest of the day nursing a headache. The elephant will smash into and keep on going like nothing happened. That's momentum :)

If the external force acting on a system is zero the momentum of the system will always be constant.this is the law of conservation of momentum.\neg:Total momentum of the system (gun and short taken together)is zero before and after rising.

You can go about this problem a few ways. A force exherted on an object will give it a certain velocity. If F=m*a, and you have the force along with the mass, you can determine the acceleration. The acceleration, of course, is the change in velocity/change in time. You'll get a velocity change per second. If you know the ball is in contact for 0.03 seconds, you can determine the final velocity, v. \n\nKinetic energy is just 1/2 * m * v^2 so that will be a simple calculation once you figure out v.

Newton's third law was the first incarnation of an important principle of physics (still valid of course) called the law of momentum conservation.\n\nIt's regarded as a consequence of other physical laws rather than a postulate as in Newton's theory. In particular it follows mathematically from the assumption that laws of physics are unchanged under translations - that space is homogeneous.\n\nIn Newton's system, the momentum lost/gained by one material object instantaneously appears or disappears in other distant objects. In that sense it's not true except as an approximation because special relativity does not allow anything to propagate faster than the speed of light.\n\nThe modern view is that there's an exchange of momentum between matter and fields rather than directly between matter and matter. The momentum density of the electromagnetic field at each point in space is given by the cross product of the electric and magnetic fields (Poynting vector/c^2):\n\n(1/4pi c)(E x B)\n\nIntegrating the momentum density over space and taking the time derivative gives the total external force (i.e. force due to charged matter) on the electromagnetic field:\n\nF = dP_em/dt = d/dt &#92;integral (1/4pi c)(E(x) x B(x)) d^3x\n\nand there is an equal and opposite force -F (the Lorentz force) on matter due to the electromagnetic field.
