Light travels in a straight line at a constant speed of 300,000 meter per second. What is the acceleration of light?


If it has a constant speed then it's not accelerating, is it?
BTW I think it's 3x10^8m/sec or 300,000,000 m/sec. It would be 300,000km/sec.

  1. Since it is moving at a constant speed it has no acceleration.
