Why Buzz Lightyear’s Rocket Launch Looks Better Than Reality

This graph states that the vertical position of the rocket increases from one frame to the other (almost) a constant amount. In physics, we call this “constant speed.” Since this position is a plot of time versus time, the slope of the line will be equal to this constant vertical speed. From the graph above, you can see that it keeps the launch speed of the rocket at 192 meters per second (m / s). It’s fast – but is it really fast enough to reach space? The answer is yes and no. Here’s why.

Here is a brief overview of escape speeds. Suppose you take an apple and throw it in the air at a speed of 10 meters per second. (This is fast enough for an apple.) As that apple moves upwards, it will slow down. Eventually, due to gravity, it will stop and then start falling towards the ground.

But we say that Apple is moving very fast at 11.186. Kilometers Per second. Then it will be so high that the gravity will not be strong enough to stop it. That apple will survive.

Buzz Light Air’s rocket is fast – but not so fast. Remember, we calculated that it was moving at a speed of 192 meters per second. But that’s not a problem, because you don’t have to worry about the speed of escape. If you have a rocket.. The engine will keep pushing the spacecraft to overcome this drag and keep moving at constant speed, so it will not fall back to the ground.

In the case of the Buzz rocket, there are basically three force interactions during this part of the movement. First, the emphasis is on engines. A conventional chemical engine burns propellant to make exhaust gas. All the forces come in pairs, so when the exhaust is removed from the engine, it pushes the rocket in the opposite direction. (The good thing about rocket engines is that they operate in both the Earth’s atmosphere and space, where there is no air.)

The other two forces on the spacecraft are the force of gravity pulling them down due to their interaction with the earth, and an air resistance force that is pushing in the opposite direction like a spacecraft. Air resistance is caused by a collision between a rocket and an air.

As soon as the spacecraft leaves the earth, these two forces will eventually become slightly smaller. This is because moving away from the center of the earth means that the force of gravity pulling on the boat decreases. And once the rocket is out of the air, there will be no air resistance, because there will be no air. Only power will be left from the engines, so the speed of the ship should increase.

But real rockets don’t work that way. In general, a rocket engine produces a force that is More Compared to gravity, this means that a rocket will travel upwards. To speed up And not just travel at a steady pace.
