Data & Discovery
We use this to visually show changes in distance over time.
What is a graph?
The faster something moves, the higher this value.
What is speed?
This invisible push or pull can cause motion to start, stop, or change.
What is a force?
Voyager’s data about distance and time could be shown using this visual method.
What is a line graph?
This describes both speed and direction.
What is velocity?
This force pulls all objects toward each other.
What is gravity?
On a graph, this axis shows time.
What is the x-axis?
A rocket changing speed or direction experiences this.
What is acceleration?
This force pushes a rocket forward.
What is thrust?
The steepest line on a graph shows this.
What is the greatest acceleration?
This property makes moving objects want to keep moving.
What is inertia?
This type of friction happens when an object moves through air.
What is air resistance?
On a distance–time graph, a straight diagonal line means this.
What is constant speed?
This term describes how much motion an object has (mass × velocity).
What is momentum?
This special use of gravity helps spacecraft gain speed without using fuel.
What is a gravity assist?
