Rocket Trajectory: Why Do Rockets Curve Instead Of Going Straight Up?

The video explains why rockets follow a curved trajectory instead of a straight line. It covers the dynamics of rocket launches, the challenges posed by air resistance, and the common misconceptions about reaching space. The main goal of rockets is to enter Earth's orbit, which requires a specific trajectory known as a gravity turn. This technique helps optimize fuel usage and reduce aerodynamic stress, allowing rockets to achieve the necessary horizontal velocity for orbit.

Why do rockets initially fly straight up very fast?

• To save fuel

• To cross the thickest part of the atmosphere

• To reach space quickly

• To avoid air resistance

What is the main goal of most rockets after launch?

• To enter Earth's orbit

• To reach the Moon

• To escape Earth's gravity

• To travel to Mars

What is a gravity turn?

• A method to increase vertical speed

• A technique to optimize trajectory using Earth's gravity

• A way to reduce fuel consumption by flying straight

• A maneuver to escape Earth's atmosphere

How does a gravity turn benefit a rocket's ascent?

• It reduces aerodynamic stress

• It uses more fuel

• It increases the angle of attack

• It speeds up vertical ascent

What happens if a rocket continues to go straight up without curving its trajectory?

• It will enter a stable orbit

• It will drift into outer space

• It will run out of fuel and fall back to Earth

• It will reach the Moon
