PHYSICS FOR SAFETY
Seatbelts (Newton’s 1st Law - Inertia): In a
sudden stop, a person’s body wants to keep
moving. Seatbelts provide the force needed to
stop your motion with the vehicle, reducing the
risk of injury.
Airbags (Newton’s 2nd Law - Acceleration):
Airbags reduce the force on passengers by
increasing the time over which momentum
changes, minimizing injury from collisions.

#7 Gravity At the tip of a ballpoint pen is a ball that rolls as you push down to write on a piece of paper. There is ink inside the pen that sits on top of the ball. Gravity pulls the ink down towards the paper, and the ball rolls in the ink as you write, taking a controlled amount from inside the pen to the paper’s surface as it turns. If you were to remove the ball that holds back the ink, gravity would pull all the ink down and onto the paper in a puddle.
#8 INERTIA When your body is moving, it takes a more powerful force to cause it to stop moving. In your car, your body is moving as quickly as the car is driving. Your seatbelt, holding you tightly to your seat, is the strong force that prevents your body from continuing to move when you hit the brakes. Without the seatbelt, a sudden stop can send you out of your seat.
#10 3 – THERMODYNAMICS
Thermodynamics: Heat from the Stove
Heat is energy that transfers from a warmer substance to a colder one. When you use a stove, the coil, flame, or cooktop transfers heat energy to the pot or pan set on top of it. Then, the heat from the pot or pan is transferred to the food inside.
#11 3 ACOUSTICS - Small speakers in your headphones use electricity and moving magnets to create sound waves. The sound waves from the speaker bounce off your eardrums, which your brain interprets as music. Sound waves that you hear, whether they come from another person or a speaker, bounce off objects and move through the air and into your ears. Your brain uses the waves to interpret where a sound is coming from and how loud it is.
#12 4 INERTIA - An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an external force.
