Difference Between Gravitation and Gravity, Derivation Formula

Difference Between Gravitation and Gravity  : Although the terms gravitation and gravity are frequently used synonymously, they have different meanings in physics. Newton's law defines gravity as the universal force of attraction between masses. In particular, gravity is the gravitational pull of Earth on objects that are close to its surface.

Gravitation and Gravity Interesting Facts

• In a vacuum, every object experiences the same acceleration from gravity regardless of mass, which is one of the fascinating features of gravity. This implies that if a feather and a hammer were dropped on the Moon, where there is no air resistance, they would both land on the surface simultaneously.
• Astronauts aboard the International Space Station (ISS) feel weightless not because gravity is absent, but because they are in a constant free fall towards Earth. The gravitational force acting on them and the station is counteracted by their forward orbital velocity.
• Gravity can alter time, according to Einstein's general relativity theory. Time seems to move more slowly in areas with stronger gravitational fields than it does in areas with weaker fields.
• The escape velocity is the minimum speed an object needs to break free from the gravitational attraction of a massive body, such as a planet. The escape velocity of Earth is approximately 11.2 km/s, which is 33 times the sound speed. To escape gravity and travel to space, you must travel at this speed.
• A century after Einstein's theory of general relativity was developed, scientists were able to confirm a prediction when they detected gravitational waves for the first time in 2015. Gravitational waves offer a new perspective on the cosmos as they are ripples in spacetime produced by the acceleration of massive objects, like black hole collisions.
