Gravity and Its Effects
- The first fundamental force described in the text is gravity, which is responsible for the attraction between objects with mass.
- One of the important medical effects of gravitational force is the loss of bone density, which can lead to osteoporosis.
- When a person becomes 'weightless', bone mineral density decreases, leading to a loss of bone strength.
- Gravity is the force that causes our weight, which is a result of the attraction between the earth and our bodies.
- One of the serious problems associated with long-term bed rest is the loss of bone density, similar to the effects of weightlessness.
