Good question. Imagine a spacecraft is approaching a planet. The planet is moving around the sun. The spacecraft path is adjusted to approach the trailing limb of the planet -- the rear edge of the planet when you look at its orbit around the sun, not its dark side. The planet pulls on the spacecraft as it goes by (and actually the spacecraft pulls on the planet, too). If the spacecraft were close enough to the planet, and traveling slowly enough, it would be captured by the planet. But it is possible to put the space craft in a path so that will not be captured--it can be pulled by the planet so that the spacecraft gains velocity. The planet loses velocity, but since planets are huge and spacecraft small, the planet's velocity is barely affected. It is hard to visualize this, but imagine a ping pong ball being struck by a soccerball in mid-air (this would make a good science class demonstration)--the ping pong ball will pick up tremendous speed by being struck by a heavier ball. The heavy ball will hardly notice it. You can do this by dropping the soccer ball with the ping pong ball on top of it. Slingshotting a spacecraft (also called gravity assist) works in a similar way except the spacecraft would be pulled by the planet's gravity instead of being pushed (as with the two-ball demonstration).
One can purchase a Lowepro Slingshot 200 from many places. A common place to buy such a slingshot is online on websites such as Amazon as well as from stores like Walmart.
The straight line distance from the Earth to Venus depends on their positions in their orbits. In terms of miles, Venus is 26 million miles away from the earth at its nearest, and 162 million miles at its furthest. Along these lines it would take between 49 and 308 years. Interplanetary journeys are not undertaken along such straight-line routes. Instead they follow a trajectory that is longer but requires less fuel through using the moon as a slingshot.
You can get a discussion of that from http://en.wikipedia.org/wiki/Interplanetary_travel Scroll down to paragraph 3.2 Cheers!
The average distance from the earth to the moon is approx 384,000 km. However, the moon's orbit around the earth is elliptical and at its closest, the moon is approx 363,000 km away while at its furthest it is 407,000 km away. So, at 50,000 km per hour, the average distance would take 7.68 hours. The minimum distance would take 7.26 hours while the maximum would take 8.14 hours. But, spacecraft do not go to the moon is a straight line - they first orbit the earth and use the earth's gravity as a kind of slingshot to propel them towards the moon. This may not be the shortest route but it is much more efficient.
A hyperbola is a conic section. Therefore, it can be produced by slicing a double cone. Half of a hyperbola, just one of its two branches, can be found by slicing a single cone. The cone must be sliced by a plane that is angled sufficiently so that it would intersect a double cone twice. This suggests a way to form one. If one points a flashlight directly at a wall, one sees a circle; moving back increases the radius of the circle. This indicates that light emerges from the flashlight in a cone shape, with its apex at the light bulb. If the flashlight is tilted, the shape of the spot of light on the wall elongates, first becoming an ellipse, then a parabola. Tilting further yields a branch of a hyperbola, as the cone is now inclined in such a way that the plane (the wall) intersects the hypothetical double cone twice. In celestial mechanics, a body that passes by a more massive body, entering its gravitational field, may, if it has sufficient energy, "slingshot" around it instead of becoming trapped in orbit or colliding. If it has exactly enough energy to do this, its trajectory will be a parabola with the massive body at the focus; if it has any more energy, its trajectory will be half of a hyperbola, with the massive body at one of the foci. The reasoning behind this is not nearly so simple as with the flashlight, however.
A straight line path from Earth to Neptune is around 2.8 billion miles. So at 100,000 mph it would take 27,900 hours - about 3.2 years. However, spacecraft never take the straight line route for their journeys. A more efficient journey is achieved through a "slingshot" manoeuvre using the gravitational effect of the moon or another planet to accelerate the spacecraft towards its destination.
because the elastic will apply more force for a longer time and therefore accelerate the rock to greater speeds
A slingshot rifle is a gun stock that has a slingshot attached to it, they are dangerous an are nit toys.

The Slingshot ended on 2009-06-09.
It is a method in which you accelerate towards a large gravitational force (usually a planet), which then also accelerates you further and you exceed the velocity necessary to break away from it gravitational field of the object, so you get a velocity boost
The warrior quickly and quietly loaded her slingshot.
Slingshot Professionals was created on 2003-03-11.
Armando Cortez invented the first slingshot around 1881
a normal ds slingshot will shoot one little rock the GOLD slingshot will shoot faster, and 3 rocks at a time
The answer depends on where you want to control it. When launched, a rocket is controlled by the movement of fins that act like ailerons on an airplane. Since there is no air in space, ailerons are of no use in space, so once in space, spacecrafts must steer by firing very small rockets and change their orbits by firing a much larger rocket. Interplanetary spacecrafts rely on small rockets as well, but they also can be controlled by taking advantage of a slingshot effect of a nearby planet. When a spacecraft nears a planet, it's speed increases. If it gets close enough to a planet, the planet's gravity can chance the path of the spacecraft and send it off in a different direction. This method has been used successfully several times over the last 40 years.
