Interaction Forces
In this video Paul Andersen explains how forces on an object always require another object. An object cannot exert a force on itself. If net forces on an object are balanced the object will remain at rest or move with a constant...

The Great Escape
Do you know how many people have been to the moon? Only 12! Part of the reason it's so few is because of how difficult it is to escape Earth and get into space in the first place. In this episode of Crash Course Kids, Sabrina talks about...

Gravitational Forces
In this video Paul Andersen explains how gravitational forces differ from the other three fundamental forces; electromagnetic, strong, and weak. Gravitational forces are always attractive and operate at all scales. Even though...

Vector Sum of Forces
In this video Paul Andersen explains how the vector sum of forces can be used to identify the net force on an object. The net force can be used to determine the overall acceleration of the object using Newton's Second Law.

Will the Moon Ever Leave the Earth's Orbit?
Every year the moon’s orbit gets a little bigger and it moves just a little farther away. Should we worry about the Moon breaking free?

Earth Doesn’t Orbit the Sun
Understanding gravity can sometimes be a bit of a balancing act, much like the fundamental laws of physics and how they inform what it is exactly that Earth orbits.

Newton's Third Law
In this video Paul Andersen explains how Newton's Third Law applies to all objects. When an object applies a force to another object (Action) and equal and opposite force (Reaction) is applied to the original object. Several scenarios...
