- Explain why one feels more pain when pricked with a pin than when pricked with a nail
- The pin is very sharp which exerts painful pressure
- The nail is not sharp and doesnot exert too much pressure
- The pin is very small thus more pressure needed
- The pin has a small contact area than the nail which exerts alot of pressure
