Newton's Laws of Motion help us understand how things move in space, especially satellites.
First Law (Inertia): If something is moving, it will keep moving in the same direction unless a force stops it or changes its path. This is why satellites can stay in their orbits; they keep going because of inertia.
Second Law (F=ma): The force of gravity is what makes things speed up or slow down in space. For example, we can figure out how strong Earth's pull is on a satellite. We use the formula ( F = \frac{GMm}{r^2} ). Here, ( G ) is a number that helps us calculate gravity.
Third Law (Action-Reaction): When two objects pull on each other, they do it equally but in opposite directions. This is important for keeping satellites stable in their orbits.
In short, Newton's laws show us how forces work together to keep satellites moving in space. Understanding these laws is key for designing satellites and knowing how things move in the universe.
