Web2 mrt. 2016 · Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects. Image source: T. Pyle / Caltech / MIT / LIGO Lab. WebFree-fall is the motion of objects that move under the sole influence of gravity; free-falling objects do not encounter air resistance. More massive objects will only fall faster if there is an appreciable amount of air resistance present. The actual explanation of why all objects accelerate at the same rate involves the concepts of force and mass.

Web8 jul. 2024 · Einstein’s theory of General Relativity explains that gravity is not a force that pulls, but rather an effect of the curvature of space-time. Gravity is one of the four fundamental forces that constitute the Universe. I’m sure that everyone is familiar with the fable about the minor accident that led Newton to the dramatic discovery of gravity. Web29 jan. 2024 · Viewed 11k times. 2. We know a mass attracts mass with a force F = G m M r 2 and the acceleration due to that force is a = G M r 2 where F = m a. Now for charges, what observations prevent us from defining F = q a where F = k q Q r 2 and acceleration due to the force is a = k Q r 2. Why can't we say the charge q which is under the influence of ... diabetic shoe pharmacy florida
