Concept featured in clip: Orbits, Gravitational pull (use of slingshot)



Connection of flickclip to the concept:This clip could be used to discuss the concepts behind the gravitational pull of a celestial body. When travelling between two planetary bodies, objects can essentially be given a free change in direction. Simply doing an about face will utilize an enormous amount of energy or fuel. When fuel is a factor, as it always is, going further in the opposite direction is more fuel efficient due to the free direction change.
