A constant speed alone does not create a g-force. In physics, "g-force" refers to the force experienced by an object due to acceleration. It is commonly used to describe the force experienced by objects in gravitational fields, such as the force experienced by objects on Earth due to Earth's gravity (often referred to as "1 g" or simply "g").
G-force is experienced when there is a change in velocity (speed or direction). Acceleration, which is the rate of change of velocity, is required to generate g-forces. This acceleration can be caused by changes in speed, changes in direction, or a combination of both.
For example, when an object undergoes circular motion at a constant speed, it experiences a centripetal acceleration directed towards the center of the circle. This acceleration creates a centripetal force, which is perceived as a g-force. The magnitude of this g-force depends on the radius of the circular path and the speed of the object.
In summary, while a constant speed alone does not create g-forces, changes in velocity (speed or direction) are required to generate acceleration and therefore experience g-forces.
