Who proved rockets could reach outer space?
The German scientist Hermann Oberth, along with others such as Robert H. Goddard and Konstantin Tsiolkovsky, made significant contributions to proving that rockets could reach outer space through their research and experiments in the early 20th century.
How do people get to outer space?
People can get to outer space by launching spacecraft using rockets. These rockets provide enough thrust to escape Earth's gravitational pull and reach the boundary between Earth's atmosphere and space, known as the Kármán line. Once there, spacecraft can travel further into outer space to visit other planets, moons, or celestial bodies.
How do rockets escape the earth?
Rockets escape Earth's gravitational pull by achieving enough velocity to overcome gravity. They generate thrust by burning fuel, propelling them upward until they reach a speed of around 11 km/s (25,000 mph) - the minimum speed needed to break free from Earth's gravity and reach space.
Can guns shoot a bullet into outerspace?
Not from ground level. Even the fastest shooting guns do not move the bullet fast enough to break the gravitational pull. Also, force is only applied to the bullet while inside the gun barrel. Rockets apply more force for a longer period of time in order to reach orbit.
Why do people make rockets?
People make rockets to explore outer space, conduct scientific research, launch satellites into orbit, and sometimes for military purposes. Rockets are essential for space exploration and enabling humans to reach beyond Earth's atmosphere.

The escape velocity from Earth is greater for larger rockets than for small ones?
Escape velocity from Earth depends only on the mass of the Earth and the distance from its center, not the mass or size of the rocket. All rockets need to reach the same escape velocity to leave Earth's gravitational pull, regardless of their size.

How much force does it take to break away from earths gravity?
To break away from Earth's gravity and reach space, an object needs to reach an escape velocity of about 11.2 kilometers per second (about 25,000 mph). The force required to achieve this velocity is enormous and depends on the mass of the object. For example, a spacecraft with humans onboard would need powerful rockets to generate enough force to break free from Earth's gravity.
What is meant by the 'escape velocity' of a rocket leaving the earth?
There is a speed, about seven miles a second, that if reached, will allow an object to overcome the earth's gravitational pull and continue into space. Rockets don't actually need to do this speed, since their objective is usually to establish an orbit around the earth.
How fast can a NASA rocket go?
NASA rockets can reach speeds of up to 25,000 miles per hour (40,000 kilometers per hour) during launch. These rockets are designed to reach escape velocity, the speed needed to break free from Earth's gravitational pull and travel into space.
What makes it possible for rockets to travel into space?
Rockets can reach space by using Newton's third law of motion, which states that every action has an equal and opposite reaction. By propelling fuel out of their engines at high speeds, rockets generate thrust that pushes them upwards through the atmosphere and into the vacuum of space. Additionally, rockets must reach escape velocity, typically around 25,000 mph, to break free from Earth's gravitational pull and enter orbit.
How do rockets get out of the atmosphere?
Basically, A extreme amount of thrust must be first produced for the rocket to reach the excessive hight needed. Once it's reached the speed needed it can easily breach the Earths Ozone layer.
