It changed the world by making scientist look different upon the world
Not sure what you mean by "change gravity"; a nebula has mass, therefore it exerts a gravitational force.
he found gravity the thing that makes us not float off into space
knowing about gravity can have much impact to improve the gravity system. the gravity system involves almost all physic knowledge. starting from the formula of the first newton and second and the third. gravity can help us with our balance in second place after our ears.
weight
A world without gravity is not a world; it is barely enough to be more than just a rock in space.
No, gravity does not change throughout the day. It remains constant, exerting a consistent force on objects.
No, it gives you weight. Mass does not change in the presence of gravity.
Weight. The force of weight experienced by an object can change when the acceleration due to gravity changes. Weight is directly proportional to the acceleration due to gravity, so an increase or decrease in gravity will result in a corresponding change in weight.
no
As compared to Earth, you mean? If an object doesn't change its shape, the center of mass doesn't depend on gravity - and the center of gravity hardly does so.
A situation where gravity causes a change in velocity is when an object is dropped from a height. As the object falls, gravity acts on it, causing it to accelerate towards the ground. The change in velocity happens because gravity exerts a constant force on the object, causing it to increase its speed over time.
the air pressure is different where if the gravity substances were to change it will be normal
