I'm Ryan! I am so exited to go to Mars! We will also learn all about acceleration and constant speed on the way!
Welcome to our rocket ship!!!!!!
Ryan, I am getting word that we are currently increasing speed! Does this mean we are accelerating?
Yes Jonny, we are increasing speed and going towards Mars, meaning we are accelerating! Speed happens when our rocket ship is moving a certain distance divided by the time we move this distance. This is so fun!
Jonny, I just realized that nobody is flying the rocket! Lets go back to the cockpit.
Once we get into the stratosphere, we will be in space! This means that we will be moving towards Mars at a constant speed! But until then, we are at a increasing speed towards space!
Ryan, we are about to hit the stratosphere! Prepare for low gravity and a constant speed!
This constant speed means that we are no longer accelerating because we are moving one direction and not changing speed, which would happen if we were accelerating!
