There is a gravitational force of attraction between every object in the universe. Gravitational forces are considered to be inherently linked to what we call ‘ mass’. there is no gravity in a spacecraft orbiting the Earth.gravity acts upwards on things that are moving upwards.It does not operate on things that are moving upwards gravity affects things while they are falling but stops when they reach the ground.gravity is caused by the Earth spinning.gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up).(Hence there is no gravity on the moon, in Earth satellites or in space as one rises above the surface of the Earth gravity lessens because the atmosphere thins) gravity is related to the presence of air, or is something in the air, so if there is no air, there is no gravity.gravity is a push from above (in some instances due to air pressure).Students may have a range of views about gravity: This idea is also developed in the focus idea Students’ views about gravity, the shape of the Earth, and the direction of ‘down’ are often intertwined. Things falling towards the Earth are such familiar occurrences that students may consider these events as ‘natural’ with no need for further explanation.Įven students who use the word ‘gravity’ in an appropriate context may not be able to be able to explain what it is, or will be inconsistent in their explanations.
