What is the thrust force of a rocket?

Thrust is the force which moves the rocket through the air, and through space. Thrust is generated by the propulsion system of the rocket through the application of Newton’s third law of motion; For every action there is an equal and opposite re-action.

Is there a difference between zero gravity and anti gravity?

Anti-gravity is anything that takes weight off your spine; Zero-gravity chairs allow your feet to be elevated above the heart.

Why are rockets stronger than gravity?

Thrust needs to be greater than weight A rocket launches when the force of thrust pushing it upwards is greater than the weight force due to gravity downwards. This unbalanced force causes a rocket to accelerate upwards. For example, if the thrust is 120 N, the resultant force is 120 – 98 = 22 N upwards.

How do Rockets make thrust?

Rocket thrust is caused by pressures acting in the combustion chamber and nozzle. From Newton’s third law, equal and opposite pressures act on the exhaust, and this accelerates it to high speeds.

Is a heavier rocket better than a lighter rocket?

Two projectiles launched at the same speed will also stay in the air for the same amount of time even if one is heavier. However, a heavier rocket won’t be able to speed up as much as lighter one with the same amount of fuel, so the lighter rocket will go faster, higher and will stay in the air longer.

How efficient are ion thrusters compared to chemical rockets?

Chemical rockets have demonstrated fuel efficiencies up to 35 percent, but ion thrusters have demonstrated fuel efficiencies over 90 percent. Currently, ion thrusters are used to keep communication satellites in the proper position relative to Earth and for the main propulsion on deep space probes.

What is anti-gravity technology?

The term “antigravity” applied loosely covers any technology that is used to overcome gravity (to float, fly, or otherwise escape Earth’s “gravity well”). When used in the strictest literal sense of the word, it actually refers only to reverse gravity fields that supposedly repel normal gravity.

What is the physics behind rocket propulsion?

Sir Isaac Newton’s third Law states that every action has an equal and opposite reaction. This is like air escaping from the end of a balloon and propelling it forward. Conventional chemical rockets burn a fuel with an oxidizer to make a gas propellant. Large amounts of the gas push out at relatively low speeds to propel the spacecraft.

What is gravity repellent propulsion?

It’s ANY propulsion method that OVERCOMES the effects of gravity rather than shielding its effects, disconnecting from its effects, reversing its effects, or otherwise using another technology to leverage against gravity. Category II.
