- Earth's gravity12345:
- Near Earth's surface, the acceleration due to gravity is 9.8 m/s 2 (32 ft/s 2)145.
- This means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.8 metres (32 ft) per second every second1.
- Earth has an “escape velocity” of 11.186 km/s (or 6.951 mi/s)235.
- Essentially, this means that a rocket needs to achieve this speed before it can hope to break free of Earth’s gravity and reach space2.
- The escape speed from Earth's surface is about 11.186 km/s (40,270 km/h; 25,020 mph; 36,700 ft/s)5.

This means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.8 metres (32 ft) per second every second.en.wikipedia.org/wiki/Gravity_of_EarthEarth’s gravity is also responsible for our planet having an “ escape velocity ” of 11.186 km/s (or 6.951 mi/s). Essentially, this means that a rocket needs to achieve this speed before it can hope to break free of Earth’s gravity and reach space.
www.universetoday.com/26775/gravity-of-the-earth/“The escape velocity of Earth is the speed at which a free object must travel to escape into space from a planet’s gravitational pull.” Earth’s escape velocity is 11.186 km/s. So, if a free body travels at this speed, it can break away from Earth’s gravity into outer space.earthhow.com/escape-velocity-earth-closed-system/Near the surface of the Earth, the acceleration due to gravity g = 9.807 m/s 2 (metres per second squared, which might be thought of as "metres per second, per second"; or 32.18 ft/s 2 as "feet per second per second") approximately.en.wikipedia.org/wiki/Equations_for_a_falling_bodyFor example, the escape speed from Earth's surface is about 11.186 km/s (40,270 km/h; 25,020 mph; 36,700 ft/s) and the surface gravity is about 9.8 m/s 2 (9.8 N/kg, 32 ft/s 2).en.wikipedia.org/wiki/Escape_velocity - People also ask

Gravity of Earth - Wikipedia
The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given … See more
