The force of gravity on Earth is approximately 9.8 m/s2. The exact gravitational force, which is described as the acceleration of gravity, differs based on latitude and altitude of a specific point on Earth. For example, gravity at the North Pole is 9.832 m/s2 and the gravity in New York is 9.803 m/s2.
Gravity on Earth is defined as the speed at which an object falls to the Earth, ignoring any effects from air resistance. An object's speed to Earth increases about 9.8 meters (32.2 feet) per second every second.
The planet with the strongest gravitational force is Jupiter, with a force of approximately 25.93 m/s2. The planet with the lightest gravitational force is Mercury, with a force of about 3.703 m/s2.
