Practical Applications
## 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.
