1472 - What can the combination of Newton's laws of motion and the law of universal gravitation be used to explain?

The combination of Newton's laws of motion and the law of universal gravitation can be used to explain many things in our universe. Here are a few examples:

1. Why planets orbit around the Sun: The law of universal gravitation explains how the Sun's gravity pulls on the planets, while Newton's laws of motion explain how the planets move in their orbits.
2. How comets and asteroids move: Gravity and motion work together to describe the paths of comets and asteroids through space.
3. The tides on Earth: Gravity from the Moon causes the oceans to bulge, creating high and low tides.
4. The falling of objects on Earth: Gravity pulls objects down, and Newton's laws help us understand how fast and far they fall.
5. The orbits of satellites and spaceships: By balancing gravity with motion, we can launch objects into orbit around the Earth or travel to other planets.

These laws help us understand how our universe works and how things move and interact with each other.
