Answer 1

The acceleration which is gained by an object because of the gravitational force is called its acceleration due to gravity. ... The formula is 'the change in velocity= gravity x time' The acceleration due to gravity at the surface of Earth is represented as g. It has a standard value defined as 9.80665 m/s. 2. The initial velocity needed to achieve that condition is called escape velocity. From the surface of the Earth, escape velocity (ignoring air friction) is about 7 miles per second, or 25,000 miles per hour. Given that initial speed, an object needs no additional force applied to completely escape Earth's gravity.......... 3.a force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving
