IN THIS LESSON…

Learn how forces like thrust, gravity, lift, and drag work together to make rockets and aircraft move.

Every object in motion is affected by forces. A force is simply a push or pull that can change how something moves. In aerospace engineering, understanding forces is essential because forces control how rockets launch, how airplanes fly, and how spacecraft travel through space.

There are four main forces commonly studied in aerospace:

  • Thrust — pushes a rocket or aircraft forward

  • Gravity — pulls objects downward

  • Lift — helps aircraft stay in the air

  • Drag — air resistance that slows objects down

Engineers must carefully balance these forces to create safe and efficient vehicles. If one force becomes too strong or too weak, the entire flight can change.

In this lesson, you will explore how forces interact and how aerospace engineers use science to control motion.

Think about:

  • What forces act on a rocket during launch?

  • Why is drag important?

  • How do engineers overcome gravity?

  • What happens when forces are unbalanced?
