    • In high school physics, a lot of time is spent analyzing the motion of objects experiencing a constant acceleration (like an object falling toward the surface of the Earth, etc.). When we take Special Relativity into account, can an object actually experience a constant acceleration? The answer is “no,” but argue why. Relatedly, can someone exert a constant force on an object? The answer is “yes” but how do you reconcile this with the fact that an object can’t experience a constant acceleration.
