Physics Wallah Foundation・2 minutes read
Gravity is integral to daily life, Newton's Apple Incident led to the discovery of gravity and Newton's Law of Gravitation describes its impact. From calculating gravitational force to understanding buoyant force, various physics concepts are explored, urging to move quickly through questions to grasp key concepts.
Insights
- Sir Isaac Newton's contemplation on the falling apple led to the birth of the concept of gravity, which states that any two objects with mass will attract each other.
- The formula for gravitational force is F = G * (m1 * m2) / d^2, with the value of the universal gravitational constant being 6.67 * 10^-11 Newton meter squared per kilogram squared.
- Acceleration due to gravity is represented by g and is calculated using the formula G * m / r^2, with the value on Earth's surface being 9.8 m/s^2.
- Archimedes' Principle explains why objects float or sink in water based on the balance of weight and upthrust forces, with water exerting an upward force on a body immersed in it.
