Let’s forget the math today and focus on Newton’s Laws.
Newton was a mathematician and physicist born in the 1600s. He existed, taught and studied well before many of our modern discoveries had been made, but his impacts are still felt today. Most importantly, for us, in this Laws of Motion.
There are 3 Laws of Motion. All have to do with force and how an object experiences force.
The First Law is commonly referred to as the Law of Inertia. This law states that an object at rest stays at rest unless acted upon by an outside force. An object in motion stays in motion unless acted upon by an outside force.
There are a few ways to interpret this → most simply, objects do not just spontaneously start moving. A force MUST be applied to them. If you ever see a ball start to roll, a book start to fall or a flag wave in the wind, it is because a force was applied.
Similarly, object do not just spontaneously stop moving. A ball will roll and roll across the ground until … it hits a wall. Or until … the force of friction slows it down.
