Here’s how the terms can be categorized based on the examples provided:
Newton's First Law of Motion (An object at rest stays at rest and an object in motion stays in motion unless acted on by a net external force.)
-
- You place a pencil on your desk, and it stays there.
-
- Matthew lets go for a recently blown up balloon, and it flies across the room as the air escapes. (This also indirectly relates to the idea of an object in motion continuing in motion until acted upon.)
Newton's Second Law of Motion (The acceleration of an object is dependent on the mass of the object and the amount of force applied.)
-
- Pushing your baby brother on the swing makes him go higher. (This directly relates to applying force to change the motion of a mass.)
-
- Karen drops a marble on the ground, and it rolls across the floor in a straight line. (Gravity applies a force causing the marble to accelerate.)
Newton's Third Law of Motion (For every action, there is an equal and opposite reaction.)
-
- A car runs into a fence, and the fence dents the car. (The action of the car hitting the fence results in a reaction which dents the car.)
Thus, the categorization is as follows:
- Newton's First Law of Motion: 2, 4
- Newton's Second Law of Motion: 1, 5
- Newton's Third Law of Motion: 3
