Science, of the physical world

Physics is how everything in the world works in harmony. Without it, things would be floating around, the earth wouldn’t rotate, and it’d be a huge mess. Newton’s laws of physics are the best way to explain how the physical world works. Newton’s first law of motion states “an object at rest will remain at rest and an object in motion will continue moving at a consistent velocity unless acted upon by a net force. A real world example of this would be playing golf. The golf ball sits on the tee with no momentum, nor force acting upon it (excluding the force of gravity). And when the club comes through to hit it, it generates a greater net force and moves through the ball with a certain velocity. The momentum from the club is then transferred from the club, to the ball. When the ball is in the air, it is moving at a constant velocity but is being acted upon by friction, which would be the air and gravity. Over a certain amount of time, the ball will eventually hit the ground, depending on its momentum and how much friction is acted on it. Another example of physical in the real world would be The Law of Inertia. This law is the idea of the tendency of an object to resist any change in momentum. A table cloth could be used to portray this law. If pulled quickly, a tablecloth can be removed from underneath dishes. The dishes have the tendency to remain still as long as the friction from the movement of the tablecloth is not too great. If pulled slowly, the friction is greater, and all the dishes will fall. All in all, physics play a major role in how things work in our world. Every move we make is a result of physics and can all be explain in a different way. Every action has a reaction, and that’s how things work in the world.
