It’s not that simple. Earth’s gravity is still pulling down on the rocket. When a rocket burns propellants and pushes out exhaust, that creates an upward force called thrust. To launch, the rocket needs enough propellants so that the thrust pushing the rocket up is greater than the force of gravity pulling the rocket … See more More than 300 years ago, a scientist named Isaac Newton laid out three basic laws that describe the way things move. One of the laws says … See more Let’s say you want to launch a satellite that orbits Earth. The rocket will launch, and when it gets to a specific distance from Earth, it will release the satellite. The satellite stays in orbit … See more If you’re trying to get to another planet, you’ll need a fast-moving rocket to overcome Earth’s gravity. To do that, you’d have to speed up to around 25,000 mph. But you’ll also need to … See more Web“Chemical, nuclear and electric propulsion systems produce thrust by accelerating and expelling propellants,” Dr Burns writes in his paper. “Deep space travel is often a trade-off between thrust and large propellant storage tanks that eventually limit performance. try not to look down challenge
