Sir Isaac newton first presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in 1686. His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force resulting from unbalanced forces acting on an object (if all the external forces cancel each other out), then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. And if an additional external force is applied, the velocity will change because of the force. The amount of the change in velocity is determined by Newton's second law of motion.

With newtons laws of motion we can expand and improve technology because the three laws are the base of rocket science
On earth, 3 kg of mass weighs 29.4 newtons (6.61 pounds).
According to Lami's theorem, if a particle under the simultaneous action of three forces is in equilibrium, then each force has a constant ratio with the sine of the angle between the other two forces.
Newton's Laws are the Laws of Missiles!
If the forces are equal then the net force is 0. If one force is greater than the other than whatever is having the two forces exerted on it will move in the direction of the greater force's direction. The total force will equal the greater force - lesser force. You can draw it in vectors to help visualize. e.g. F1 <------------------*-------> F2 let's say F1 = 5 newtons and F2 = 2 newtons. The combined force would equal 3 newtons going <- direction.
Newton's three laws of motion describe how forces affect motion. They have nothing to do with gravity, except that gravity is one of many possible causes of force.

three forces are gravitational,,electromagnetic,and weak nuclear
Forces are derived from the first derivative of energy. The five forces are: F=[d/dr,del][Es,Ev] = [dEs/dr -Del.Ev, dEv/dr + Del Es + DelxEv]. There are two scalar forces and three vector forces as shown above. Forces and energy are quaternions, consisting of a scalar and three vectors.

Kinematics does not take forces explicitly into account. Instead, kinematics works with the motion of objects (speed or velocity). Dynamics will take forces into account explicitly. Common examples of the two would be projectile motion of objects (constant acceleration equations) and Newtonian dynamics (Newtons three laws...the second law is the sum of the forces).
On earth, 3 kg of mass weighs 29.4 newtons (6.61 pounds).
Plane forces are confined to a plane or are not three dimensional, while space forces are three dimensional..
Because one of the three forces is equal and opposite to the resultant of the first two.
According to Lami's theorem, if a particle under the simultaneous action of three forces is in equilibrium, then each force has a constant ratio with the sine of the angle between the other two forces.
