light travells in a straight line at a constant speed of 300,000 km/sec. what is the light's acceleration?

the key word is "constant." a=(v2-v1)/t. The final and initial velocity is equal. What does that do to the acceleration if I do not increase or decrease in speed? Plug it into the equation and let's see... a=(300,000km/sec-300,000km/sec)/time

tnx :)

To determine the acceleration of an object, we need to consider its change in velocity over a specific time period. However, light always travels at a constant speed in a straight line, so its velocity remains unchanged. Therefore, the acceleration of light is zero.

It is important to note that acceleration is the rate of change of velocity, not simply the speed of an object. Since light's speed is constant, there is no change in velocity, and thus the acceleration is zero.
