Students will learn how length contraction follows from time dilation and the meaning of the gamma factor.
Watch a clock slow down in the strong gravitational field near the event horizon of a massive black hole.
Explains why there is time dilation for objects moving close to the speed of light.
A list of student-submitted discussion questions for Length Contraction.
This study guide gives an overview of special relativity and general relativity: a look at time dilation, length contraction, relativistic mass and kinetic energy, twins paradox, and spacetime.
