Why is it a rocket🚀 is used to go straight up into outer space and not just use an airplane ✈️ ? I’m sure there is a good reason but it seems that the gradual assent would be preferred over the straight up approach.

Atmosphere has thinner air as you go up.
Make a paper plane and throw it inside your home.
Now go outside and do the same. If it’s hot outside, the air would be thinner and it would travel slightly less. If it’s cold, it would travel a bit more.
So, planes require air to lift themselves up. Once you go up enough, you can’t go further as there’s no air to support.
Rockets on the other hand are like pogo sticks. They use own energy to go up. So, they can reach space.
