# Newton's First Law

## Newton's First Law

"Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it."

## How I Fly

Hi, I'm Pablo Plane and I will tell you how I fly. First of all, I have to use my inertia to gain speed and put myself in motion. If my thrust is increased, the drag depends on the wind speed. This is a key factor in how fast I will accelerate. In addition, when my drag is equal to the thrust, I will no longer go faster but instead now I will have a higher constant speed.

## When I am Still

When I am still, my engine stops moving. When my engine stops moving, I do not have the power to gain speed and put myself in motion. This affects my acceleration and me. Since the speed of the wind is dependent to the drag, I will no longer be able to move. This is quite boring.

## Reference Points

When I am about to leave, I start my engine increasing my speed. I start by passing the flight tower. The journey begins! Now that I'm in air, I pass that distant building glimmering in the clouds. Wow, the wind is cold!
