Applications of Newton's Laws in Real-World Situations - JSS2 Basic technology Lesson Note

Transport and Vehicles:

• First Law: Seat belts in cars are designed to keep passengers in place, preventing them from continuing to move forward when the car suddenly stops. 
• Second Law: Engineers calculate the required engine force to achieve desired acceleration for cars, trucks, and other vehicles.
• Third Law: Jet engines push air backward to propel aircraft forward.

Sports:

• First Law: A soccer ball remains stationary until kicked.
• Second Law: The force applied by a bat to a baseball determines how fast and far the ball will travel.
•  Third Law: Swimmers push water backward to move forward in the pool.

Everyday Life:

• First Law: A cup of coffee on a table remains at rest until someone picks it up.
• Second Law: Lifting heavier objects requires more force, so you exert more effort to lift a full bucket of water than an empty one.
• Third Law: Walking involves pushing the ground backward with your feet, and in return, the ground pushes you forward.
