Why Do We Need To Know About Newton's 1st Law Of Motion
Learning about Newton’s 1st law of motion helps us understand why things move or don’t move. Engineers use this knowledge to make sure things like cars, buildings, and bridges work correctly and safely under different conditions.
This law is also really important for making cars safer. For example, engineers use it to design safety features like airbags and areas in cars that can crumple in a crash. These features help keep people safe by managing the forces involved when a car stops quickly or crashes.
