For my Physics this last quarter, I learned about Newton’s Three Laws of Motion. With Physics, you can basically see it all around us. That’s why I titled this post “As Seen In” because you’d see everything here “as seen in” the world!
1. An object at rest/motion will remain at rest/motion unless acted upon by an outside force. (Also known as the law of inertia!)
You can see Newton’s first law of motion when people play billiards! A billiard ball will stay in its position unless it is hit by another ball! This is also why we have to wear our seatbelts. When we ride a car, we start at the same velocity the car is travelling. When the car breaks, we would be travelling at a much greater velocity causing us to move forward.
2. Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
This law explains the equation for F=MA (force = mass x acceleration). Also, everyone pretty much knows that heavier objects require more force to move the same distance as a lighter object. It would take much more force to move a car the same distance that we kicked a soccer ball.
3. For every action, there is an equal and opposite reaction.
This means that for every force, there is a reaction force that is equal in size, but opposite in direction. When an object pushes an object, it gets pushed back in the opposite direction equally hard. A good example for this is when we get off from a boat and back onto the shore. As we step move onto the direction of the shore, the boat will move the opposite direction.
So that’s how Newton’s Three Laws of Motion are, as seen in the world! What other examples of these three laws do you see in everyday life?
