Newton's Laws of Motion help us understand momentum in physics.
First Law (Inertia): If something isn’t moving, it won’t start moving unless something pushes or pulls it. This means that momentum (which we can think of as how much "oomph" something has when it moves) stays the same unless something else acts on it.
Second Law (F=ma): This law explains how forces change momentum. When you push or pull on an object, it changes how fast it's moving over time. We can express this with the formula ( F = \frac{dp}{dt} ), which is a fancy way to say that force changes momentum.
Third Law (Action-Reaction): Every time you do something, like push a ball, the ball pushes back with the same amount of force but in the opposite direction. This shows how two objects share momentum when they bump into each other.
In short, by learning about these laws, we get a better idea of momentum and how it works when things move.
