The rubber sheet analogy for einstein s general relativity model of gravity is a popular way to visualize the effect mass has on the curvature of spacetime.
Gravity rubber sheet analogy.
But a ball rolls on a surface because gravity is pulling it down.
My single group quasi experimental study with repeated measures was designed to assess the effectiveness of the rubber sheet analogy in teaching gravitational fields.
Since i read cosmos long ago i see the same analogy about the balls rolling on a rubber sheet used to explain how gravity works.
The rubber sheet analogy for einstein s general relativity model of gravity is a popular way to visualize the effect mass has on the curvature of spacetime.
The rubber sheet or trampoline analogy for gravity is flawed because it is not fully three dimensional as a real star and planets would be.
The right hand side of this pair of drawings is closer to real life but still not accurate.
My single group quasi experimental study with repeated measures was designed to assess the effectiveness of the rubber sheet analogy in teaching gravitational fields.
In space it will follow a straight line and go over any hole on the surface.
That the warping of spacetime to produce gravity is like the deformation of a rubber sheet by a central mass.
Experiments reveal that deformed rubber sheet is not like spacetime.
