Understanding Earthquakes with Newton's Laws of Motion

Earthquakes can be tricky to understand, but we can use some simple ideas from Newton's Laws of Motion to help. Here are a few important points:

1. Force on Buildings: One of Newton's laws tells us that force equals mass times acceleration (that's $F=ma$). This helps engineers figure out how much force hits buildings during an earthquake. With this knowledge, they can build stronger structures that can handle these forces.

2. Inertia: Newton's first law talks about inertia. This means that things like to stay still or keep moving in the same way unless something pushes or pulls them. When the ground shakes, this inertia can make furniture slide around or even fall over, causing damage.

3. Action and Reaction: Newton's third law says that for every action, there is an equal and opposite reaction. This idea helps us understand how the waves from earthquakes move through the ground and how they can affect nearby buildings.

These ideas are really important because they help us reduce damage from earthquakes and keep people safe.
