Fg=m•g || IE: Weight = mass x gravity
Therefore, the relationship are as follows:
mass and gravity are inversely proportional
mass and weight are directly proportional
weight and gravity are directly proportional
These applications DO NOT INVOLVE harmful ionizing energy:
- MRI
- ultrasound
- laser surgery
