Are you looking for "equal" and "opposite?"

Basically you have the right idea. Use momentum (mass x velocity) for the motion and the sudden change in speed and/or direction (acceleration) and you get force x time = kinetic energy trying to rip you apart or squash you like a bug.

I am terribly afraid of the equilibrium problem.. the first one on the free response!!! well, good luck!

Power:\nP=dE/dt = dW/dt\n\nForce:\nf=ma\n\nEnergy:\ne=mc^2

mass in motion stays in motion unless disrupted by another force!

All actions / reactions have consequences---good actions usually have good consequences and bad actions usually have bad consequences.

1.Objects at rest tend to remain at rest, and objects in motion tend to remain in motion in a straight line at constant speed.  2. Force=Mass times Velocity. 3. Every action has an equal and opposite reaction.

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"

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

ahh, good theory problem...\nlet's see, there's energy, friction, force (normal, tension, as well as the other ones mentioned), gravitation, mass, pendulum motion, gotta be more that I've missed, but no doubt someone'll be here to correct me.

the major action/reaction pair is :\nthe air escaping from the baloon- action.\nthe rocket reacting by moving forward- reaction.\n\neverytime the rocket veers from a straight line path this is another action.  the reaction is the force of the rope on the straw holding the rocket on track

Yes, they dont call it a Law for nothing.\n\nThink of any "action"....for example, Jumping.  Now think of the "reaction" involved...the Normal force.\nWhen you jump, your legs exert an "action" force down in the ground.  In reponce, the ground exerts a "reaction" force back on your legs called the "normal" force.  We know the ground exerts this force because otherwise, the ground would immediately begin to accelerate downward as soon as you tried to jump.\nBut the normal force is even exerted when you are just standing still.  Earth's gravity exerts a force on you downward (likewise you exert a force on the Earth upward) and if the ground did not push up, you would fall through the Earth.\n\nFor every action, there is an equal and opposite reaction.

The net force needed is zero.  Force is mass * acceleration, and acceleration suggests a change in velocity.  For constant speed and direction, the acceleration is zero, and hence the net force is zero.  When moving at constant velocity, the frictional and drag forces (which work to slow the car) and the drive force of the engine are exactly equal and opposite.  The net force is the sum of these two opposite forces, and hence the net force is Zero.

the answer you are looking for is n the words that you used ( force ) a push is a force , and so are many other ways that energy is transformed in to other forms of work ,force is kind of a name used to tell you what kind of transformation the energy is taking , or thats the way it was explained to me in school many moons ago

as the table is frictionless a constant force will take it to infinity...... it will never stop....

Not always. If the object is in motion, then no. The total energy, aka total mechanical energy is always constant due to the Law of Conservation and Energy. It depends on the problem. Certainly,if you know the total mechanical energy in the system than you can find a variable for the kinetic energy or gravitational potential energy,assuming you given other variables.

All three Newton laws are real. They do support other two law, there is no conflict in them.
