Newton's First Law
Imagine you're on a skateboard. When you push off the ground with your foot, you set the skateboard in motion.
Once the skateboard starts rolling, it keeps moving until something causes it to stop.
If you want to stop, you might press down on the back of the board, making it scrape against the ground.
This scraping generates friction, which slows the skateboard until it eventually stops.
Even if you don’t try to stop, the skateboard will still stop because of friction between the wheels and the ground.
In areas with extremely smooth surfaces, where there is little to no friction, objects keep moving unless an external force stops them.
This phenomenon is explained by Newton’s First Law, also known as the Law of Inertia.
This law says that an object at rest stays at rest, and an object in motion keeps moving unless acted upon by an external force.
Inertia is an object’s tendency to resist changes in motion, which is why this principle is called the Law of Inertia.
