Study Notes
Gravitation
- Defines as the attraction between two bodies in the Universe, enabling various interactions.
Effects of Force on an Object
- Can alter the shape of an object, demonstrating physical deformity under pressure.
- Influences the size, suggesting that external forces can change physical dimensions.
- Capable of changing the direction of a moving object, impacting its trajectory.
- Initiates motion in an otherwise stationary object, highlighting the necessity of force to overcome inertia.
- Can halt a moving object, demonstrating the ability to counteract momentum.
- Responsible for altering the speed of an object, illustrating the concept of acceleration.
Gravitational Force
- Identified as a universal force acting between any two bodies, crucial for the dynamics of celestial bodies.
- Discovered by Sir Isaac Newton in 1665, marking a significant advancement in the understanding of physical laws.
Properties of Gravitational Force
- Acts vertically downward, always directed towards the center of the Earth, indicative of Earth’s mass.
- Maintains a perpendicular relationship to the Earth's surface, emphasizing its consistent behavior regardless of location.
