Staying Safe and Healthy with Physics
Hospitals, doctors, and emergency services use physics every day to keep people safe and healthy.
Real-World Benefits
- X-rays and MRI: Help doctors see inside the body without surgery.
- Seatbelts and Airbags: Use principles of forces and energy to protect you in a car crash.
- Lasers: Used in eye surgeries and to scan barcodes in stores.
How Physics Saves Lives
By understanding energy, forces, and waves, we can create safer cars, smarter treatments, and better health.
Examples
Doctors use X-rays to find broken bones.
Airbags in cars cushion you during an accident, absorbing energy.
