The product of (force x time) is the quantity called 'impulse'. It has the same
units as momentum and, indeed, an impulse imparted to an object increases its
momentum by that amount.
In the metric system, it's easy. A newton-second is a kilogram-meter per second.
But in this case, all you have for impulse is something called a "poundal-second",
which I have no idea what other unit that may be equivalent to. I don't even know
what the unit of momentum is in the 'customary' system. Foot-pound per second ?
Slug-mile per hour ? Who knows ?
If the force does not vary, this product is called the impulse. If the force varies over time, the impulse is the integral of force with respect to time.
Impulse
they both are always making time and is always in motion
"10 miles per second" is not an acceleration, it is a speed. An acceleration has two time units, or a time unit squared, for example, "9.8 meters / second2".
A falling object, such as a ball, can stop very quickly (in a thousandth of a second or thereabouts) but nothing stops instantly. To stop in zero time would take infinite force.
The net force on an object is equal to the mass of the object multiplied by its acceleration.The second law of motion states that:FORCE=MASS*ACCELERATIONA body of mass m subject to a net force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body.

Impulse - APEX ! =)
Impulse
No, impulse is not the product of average applied force and the duration of the force. Impulse is the integral of the force with respect to time.
True
Time Force is a time and attendance software. Many different businesses and companies might utilize the Time Force software to help track employee hours.
Work is the scalar product of Force acting and displacement produced in the direction of the force. So it is independent of time.
It usually means a sudden urge to to something. In physics it means 'the product of force and the time for which it acts', or force times time.
The only equation that comes to mind is the one for impulse. An impulse is a force applied for a limited time. > Velocity change = (force * time) / mass > Example : A 10 kg mass is travelling at 100 m/s, a force of 100 newtons is applied for 5 seconds in the same direction as the motion, calculate the new velocity. > Velocity change = (100 * 5) / 10 = 50 metres per second Add to original velocity = 100 + 50 = 150 metres per second
Einstiens law of relativity. That does not relate to impulse. Impulse equates to a change of momentum, usually thought of as for a very short time, but doesn't have really to be so short. Now since force = mass times acceleration =m.dv/dt, you can write that as d/dt of mv, so force =rate of change of momentum So force times time (or its integral over time, which is the same thing) must equal simply the change of momentum. In the case where it a very short time, all that happens is that the momentum changes instantaneously.
If the force is constant (doesn't change over time), the impulse (change in momentum) is simply the product of force x time.
Rate of change of work with respect to time is Power:d/dt(Work)=d/dt(Force x Displacement) {W=F.d}=Force x d/dt(Displacement) {If Force const. with time}=Force x velocity=Power
