  1. Gravitational field strength, g, is defined as the force per unit mass, g = F/m. From Newton's second law and the definition of the newton, free-fall acceleration, g, is also equal to the gravitational force per unit mass. The units of gravitational field strength, N kg -1, and free-fall acceleration, m s -2, are also equivalent
  2. A gravitational field is the area around the body that is exerting the gravitational pull. It can be defined as the gravitational force felt by a unit's mass placed at a point in space. The gravity of earth causes free-falling objects or people to accelerate towards the ground at 9.8 meters per second squared
  3. The formula for gravitational field intensity is given by, g = F/m = 10/5 = 2 N/kg. Example 2: Calculate the gravitational field if the mass and force of a substance are given as 6kg and 36N respectively. Solution: The given parameters are, F = 36 N and m = 6 kg.

The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light

Anti-gravity (also known as non-gravitational field) is a hypothetical phenomenon of creating a place or object that is free from the force of gravity.It does not refer to the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of gravity with some other force, such as electromagnetism or aerodynamic lift.Anti-gravity is a recurring concept in science. Gravitational energy is the movement of an object or mass that is caused by the pull of gravity. This is caused on Earth by the strong attraction of all other masses to be drawn back to Earth's center. An example of gravitational energy is water from a river tumbling over a cliff to form a waterfall. When an object is lifted from the ground.
