Study Notes
Introduction to Gravitation
- Gravitation is the force of attraction between any two masses.
- When a stone is raised and then released, it falls towards the Earth due to gravitational force.
- Gravity acts as the force causing objects to move downward when released from a height.
- The Earth attracts all objects towards its center; this is why they fall when dropped.
- To lift an object off the Earth's surface, an external force must be applied to counteract gravity.
- Sir Isaac Newton theorized that every object attracts every other object through gravitational force.
- For smaller bodies, gravitational force is minimal and often undetectable.
