Force's relation to energy.?
918305
If you apply a force to move an object, you produces work, and this work is equal to the kinecti energy change.\n\nThe speed of light is not force!!!!

F = ma\n\nF - Force\nm - mass\na - acceleration

A force is a push or pull upon an object resulting from the object's interaction with another object.\n\nThe formula is F=ma, where F= force, m=mass, a=acceleration

Yes acceleration and force should have a linear correspondence in this experiment (noise excluded). Obviously Force = Mass * Acceleration.\n\nIt is difficult to give much more qualitatively without a better description though.

In what domain? \nWith what force?\nWith what resistances?

All forces ultimately resolve to so called "Magnetic", "Electrostatic" and "Nuclear" forces - all of which are explained as "action at a distance" via a "field".\nSince none of these actions at a distance can be explained except via artificial theories such as "ghost particles" in Quantum physics or "space/time distortions" as in Relativistic physics, your question is very valid and the simple answer is no-one knows what a "force" really is or how it is produced.

This problem is solved with the application of work and energy principle which states that total work done on a moving particle is equal to the change of its kinematics energy:\nW=T2-T1\nHere the only work done on the particle is dot to gravitation force and is equal to -m*g*h:\n\n-m*10*0.45 = (1/2)*m*(1)^2-(1/2)*m*(v)^2 --->\nm*v^2=(4.5+0.5)*m*2=10*m --->\nv=sqrt(10) m/s\n\nv is equal to sqare root of 10.(approximately 3.162 m/s)

Energy= Mass times the speed of light squared... It is the relationship of mass to energy. And it expalins the potential of fizzile material in atomic weapons (thermonuclear H bomvs) are more efficeint.

No common denominator for the energy in the things you mention except that if it has mass, then it embodies the energy given in E = mc^2\n\nThis applies to ALL matter.

Well, as you've written it, it's a matter of differentiation the first equation, which gives you the second, as long as you take the limits of the integral properly.\n\nObjects in a potential field have an energy due to that field, dependent on their position, x. They will tend to move in a direction that lowers their energy, and experience a force due to the field that pushes them in the right direction. Hence, after some maths, the second equation - the force experienced due to a potential field is equal to the rate of change of that potential with respect to position - if the potential field changes rapidly, the force will be stronger. The minus sign means that the force moves you from high energy to low energy, ie, U decreases as the force moves you.\n\nThe first equation states much the same thing, the change in potential energy is from the force acting over a distance. This is usually how potential energy is defined, in case you're wondering where is came from.\n\nWrite Delta u as U(0) - U(x): the change in energy, moving from your starting point x=0 to some other point. Then the integral is\n\nS F(x) dx, with upper limit of x and lower limit of 0.\n\nDifferentiate both sides. The "U" side gives you -dU/dx, because U(0) is a constant, and the "F" side gives you F(x).\n\nIt's hard to explain any further without diagrams and stuff. Most first year college physics texts have more detailed explanations, better than I can. Hope this helps.

A force is conservative if it can be described as the gradient of a scalar potential. So for instance gravity is conservative because it is proportional to the gradient of the gravitational potential energy.

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.

force = constant * distance\nF=kx\nforce = mass* acceleration\nF=ma\n\nx=F/k\nx=m*a/k = 4.0*9.8/800= about .05m, or 5cm

well force is measured in kg*m/s^2 so, force will cause a function of time and distance to increase exponentially over the interval of the force applied.\n\nFor example, an object dropped from 100 meters will go 5 meters in the first second, 20 meters in the 2nd second, and  25 meters after 3 seconds, etc.

cmon...dont u know basic physics...just calculate the resultant of these 2 forces\nanswer= [(132)^2 + (181)^2]^1/2\nif this makes sense!!
