While an object falls faster and faster, the backwards force of air resistance will increase. Once the force of air resistance equals the force of gravitation, the object will no longer accelerate, and is said to have reached "terminal velocity".While an object falls faster and faster, the backwards force of air resistance will increase.

gravitational force
This is a sentence! A megaton is an explosive force of 1 million tons of TNT.
The lift and thrust force makes an airplane go faster.
If the pendulum was pushed with a large force or if it was heavier. It might swing faster.
Driving or bursting out with violence and noise; causing explosion; as, the explosive force of gunpowder., An explosive agent; a compound or mixture susceptible of a rapid chemical reaction, as gunpowder, or nitro-glycerine., A sound produced by an explosive impulse of the breath; (Phonetics) one of consonants p, b, t, d, k, g, which are sounded with a sort of explosive power of voice. [See Guide to Pronunciation, Ã 155-7, 184.]
Gunpowder is a mixture of three ingredients: potassium nitrate (75%), charcoal (15%), and sulfur (10%). These ingredients react together to produce a rapid and exothermic reaction, which is what creates the explosive force of gunpowder.
Gunpowder of itself is not actually explosive, but rather flammable. Gunpowder is designed to burn at a very specific, controlled rate in order to lend a certain consistency to the various products that use gunpowder (that is, if you were to build fireworks or explosives like dynamite one could depend upon the same burn rate for a particular kind of gunpowder). If gunpowder were to be poured on the ground and lit, it would simply burn, sometimes rapidly, but no explosion would occur. The 'explosive' nature of gunpowder comes from the release of a variety of gases produced during the burning process. This gunpowder-burning process is initiated by igniting what is known as a primer: a veryrapidly flammable (explosive, even!) substance that reacts to various energy input such as heat or shock - a fuse or firing pin). Typically, these gases are contained or restrained (e.g., in a shotgun shell or a firecracker) until a predictable amount of gas has accumulated, sufficient to cause a sudden, almost instantaneous release of this gas through a predetermined outlet: the forcing out of the paper or plastic wadding of a shotgun shell, or simply the restraining force of a firecracker's paper shell. The explosion (near-instantaneous release) of these gases is what propels shotgun pellets or fireworks particles outward in the familiar explosive pattern.+1Answers.comAnswers.com
The explosive force is the reaction of potassium with water liberating hydrogen.
Gun powder by its self does nothing ... gun power is an incendiary meaning it burns at a high temperature... making it good to project or propel object at a great distance...Gunpowder is what is known as a "low" explosive. Gunpowder, when ignited by flame or friction (i.e. it is heat in some form that cause gunpowder to ignite), burns rapidly. This rapid burning of the gunpowder grains results in a significant amount of gas being produced. This hot gas expands quickly, producing a wave of force.In a confined space, this gas will attempt to push against the walls of whatever is confining it. It thus makes for an excellent propellant - gunpowder produces a steadily increasing amount of gas over a relatively long time period (hundreds of milliseconds), allowing it to slowly accelerate a projectile out of a barrel.In comparison "high" explosives (such as TNT) don't actually burn in the sense of combining with oxygen in a typical oxidation process. Rather, they detonate, and producing a supersonic shock wave of force, and it is this wave which exerts extreme force on objects. Compared to gunpowder, the shock wave from a high explosive is produced about a 10 times faster than the burning gases, and is well over 10 times more forceful. High explosives generally make very poor propellants, since this large force acts over too short a time frame to push a projectile out of a tube - rather, using a high explosive substance as a propellant will most likely burst the barrel or destroy the projectile.
megaton (or megatonne)
splitting or explosive force

A megaton explosion.
It requires an explosive force to hurl and fragment the molten rock like that. Non explosive eruptions extrude rock more "gently".
Yes. The gas is actually the primary driving force behind explosive eruptions.
