Defining Gravity
So, if gravity pulls everything down, then why don't things on the bottom of the Earth get pulled down into space? In this episode of Crash Course Kids, Sabrina talks about gravity and explains that when we talk about gravity pulling...

Newton’s Third Law and Gravitational Force Review
Newton’s Third Law states that for every force exerted by one object on another, the second object exerts an equal and opposite force on the first. These forces act simultaneously and are external to the system, meaning they don't change...

Why Can't We See the Dark Side of The Moon?
One of the most important things we have learned about the Moon is that while it revolves around the Earth, it always points the same face toward our planet. That is the only face we see when we look at the Moon from home. In fact, we...

Resultant Forces
A force is a push or a pull that acts on an object. Forces are vector quantities because they have both magnitude and direction, and so can be represented by an arrow. Scalar quantities have only magnitude and no direction. When several...
