Impulse-momentum theorem
The theorem that states impulse equals the change in momentum is known as the impulse-momentum theorem. It relates the force applied to an object over a period of time to the resulting change in its momentum. Mathematically, it can be expressed as the integral of force with respect to time equals the change in momentum.
Newtons First Law of Motion states that an object with a given momentum will continue to posses that same momentum until the object is acted on by a force in which case it will undergo a change in momentum. Inertia is a measure of an objects tendency to resist a change in momentum. Massive bodies have a large inertia. If a massive body is in motion its momentum is given by the product of the mass and the velocity of that body. Newtons first law says that if a force acts on this body its momentum will change. But since the body has a large inertia this change is small. For example, if a small space pebble collides with a large asteroid that has a constant velocity and thus constant momentum, the force is small relative to the inertia of the asteroid so the momentum only changes a little bit.
The law of conservation of momentum (for example linear momentum), says that if no external forces act on a body or if the sum of all external forces on the body is zero, then its momentum remains constant. This means that if I don't push an object that in its initial state stands still, than this object will remain still. And then again: if I don't exert a force (push or pull etc.) upon an object that moves with a constant speed, then its speed will remain constant.

Yes. From Newton's Second Law, you know that to accelerate an object, a net force must be applied to it. The impulse-momentum relationship is basically the same thing, but worded differently. It says that if you wish to change the momentum of an object, you need to exert an impulse on it.From: Conceptual Physics, by Paul Hewitt. 11th Edition, Ch. 6 pg. 89.
it could be said that since potential energy (mgh) is lost at the exact rate kinetic energy (ke) is gained, that energy is translated into another form since force applied (gravity) over time then impulse applied and increase of momentum
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
i act on impulse. hes an impulse buyer. i never think before i act, i just do what my impulse says. sorry i know theyer not the best...

Neither. A theorem is a proven mathematical statement. This says nothing about how easily it can be proven. e.g. the Pythagorean Theorem is easily proven, but Fermat's Last Theorem is extremely difficult to prove.
in automatic control the nyquist theorem is used to determine if a system is stable or not. there is also something called the simplified nyguist theorem that says if the curve cuts the "x-axies" to the right of point (-1,0) then the system is stable, otherwise its not.

The midpoint theorem says the following: In any triangle the segment joining the midpoints of the 2 sides of the triangle will be parallel to the third side and equal to half of it
