Escape Velocity from Every Planet in the Solar System: Resource for Kids

What is escape velocity?

In physics, escape velocity is the minimum speed needed for an object to "break free" from the gravitational attraction of a massive body (that is, to escape a massive body without ever falling back).
In other words, an object has to overcome the gravitational pull of a massive body for being free to escape into space.
For example, a rocket going into space needs to reach the escape velocity in order to make it off Earth and get into space.
A larger planet has more mass and requires a much greater escape velocity than a smaller planet with less mass.

More particularly, escape velocity is the speed at which the sum of an object's kinetic energy and its gravitational potential energy is equal to zero.

So, if the kinetic energy of an object, launched from the Earth, were equal in magnitude to the potential energy, then in the absence of friction resistance it could escape from the Earth.

A rocket moving out of a gravity well does not actually need to attain escape velocity to escape, but could achieve the same result (escape) at any speed with a suitable mode of propulsion and sufficient propellant to provide the accelerating force on the object to escape. Escape velocity is only required to send a ballistic object on a trajectory that will allow the object to escape the gravity well of the mass M.

In closing, for example the escape velocity from Earth is about 11.2 km/s or 40,270 km/h (25,020 mph).

This topic isn't so simple, therefore an animation like this below can help its understanding, in particular by the kids.

I'm pretty certain I could still muster a great looking pencil drawing. Alas, I no longer have the tools available with the exception of my compass set, circle and miscellaneous  templates, scales and such. No board, nor drafting machine.

Introduction
I began my career as a draftsman in 1972 after 4 years of drafting classes throughout high school. Several years later I became a machine designer when I worked for Daley Design, a well respected local company doing contract design work and eventually a special machine builder. After a number of years with Daley Design I moved on to a few local companies including Yates American Machine, Barber Colman Automated Mfg. Systems Division, Clinton Electronics, and Atwood Industries. In 1991 I started my own company Engineered Design Solutions after conceiving an idea for a new drinking straw and designing a special machine to produce the straw. I ultimately received an order to build the machine which allowed me to strike out on my own.
 
Here's a few quotes (of my own making) I hope you like and share:

We all walk along the escarpment. Some closer than others.

Oxymoronically, virtual reality is literally a real thing.
 
I, for one, am glad that the wheel has been re-invented. Multiple times.
 
Innovation: Seeing a sealed box then creating its contents.
 
Conquer space travel and time travel will take care of itself.
 
The key to time travel is live minute to minute and don't sweat the minutiae.
 
If it weren't for industrial art, art museums would still be caves.

Confusius say: He who overfills Zippo lighter make rash decision.
 
When mandated, innovation isn't.
 
I try to stay away from highfalutin words, but invariably fail.
 
Bragging rights
