Newton's First Law of Motion: Balanced and unbalanced forces
Newton's laws are very important because they tie into almost everything we see in everyday life. These laws tell us exactly how things move or stay at rest, like why you don't float out of bed or fall through the floor of your house. They apply any time you have forces acting on masses, and that’s as true in deep space as it is on Earth.
On this page, you will find some information to boost your knowledge of Newton's first law of motion, which states that:
"An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force".
