    Can you correct me with space travel using orbits?

    lets say we are going from Earth to Jupiter you cant go there in a straight line because it would take a lot of speed right? so instead of going in straight line, we leave the Earth tangentially so that we can orbit around the sun which helps the rocket gain speed...we also leave the Earth at a...

    Physics - orbits of satellites etc?

    An Earth (mass M) satellite of mass m is in a circular orhit of radius r1. It is moved to an orbit with a larger radius r2, by way of an intermediate elliptical orbit, This is achieved by firing rockets for a short period when it is in the inner orbit and then firing the rockets again when it...

    Science test help. . . Orbits, Satellites etc. ?

    Hi! I am a 13 yr old girl and I have just switched groups at my school, causing my whole timetable, topics and teachers to change. In Science I have a test coming up on Wednesday and have not been their for the topics of Space. It goes into quite alot of detail and I would be very very grateful...
