That depends on what your light ray is traveling through. If through vacuum,

then its speed is 299,792,458 meters per second. If through anything else but

vacuum, then (299,792,458 meters per second) divided by (the index of refraction

of that material.

Light from a star travels to earth in a straight line at a constant speed of almost 300000 km s what is the acceleration of light?

The speed of light is constant at about 300,000 km/s in a vacuum, so light does not experience acceleration.


How would you describe your motion in terms of velocity and acceleration as you ride in a car down the street come to a red light wait for the green light and then start off again?

As the car moves down the street, the velocity is positive. As it comes to a red light and stops, the velocity decreases to zero. Waiting at the red light, the acceleration is zero. When the light turns green and the car accelerates, the velocity increases from zero to a positive value, and the acceleration is positive.


What is a simple example of acceleration?

A simple example of acceleration is a car speeding up from a stationary position at a traffic light. As the driver presses the gas pedal, the car's speed increases, showing acceleration.


If Light travels in a straight line at a constant speed of 300000 kilometers per second What is the light's acceleration?

Light does not accelerate as it always travels at a constant speed of 300,000 kilometers per second in a straight line, as per the laws of physics. This is because light does not have mass and therefore does not experience acceleration in the same way that objects with mass do.


What does not have direction force weight acceleration or mass?

Light does not have weight, acceleration, or mass. It does have direction and can exert force, as seen in phenomena such as radiation pressure.

What are exmaples of acceleration?

When you are stopped at a light, and it turns green, you start to drive forward. That is acceleration.


What is the acceleration of light from a star?

The speed of light is constant in a vacuum and is approximately 299,792 kilometers per second. Light from a star travels at this speed from the star to Earth without acceleration.

Negative acceleration


How many g's is the speed of light?

speed of light is constant velocity and does not accelerate so there is no g force

What is light's acceleration if its traveling at a constant speed of 300000 km s?

It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.

What does ASR dash light mean in Isuzu NPR truck?

The ASR dash light is a brake assist system/acceleration slip regulation light. When this light comes on in the Isuzu NPR truck, the on board computer in the vehicle detected a malfunction in the acceleration slip regulation and the vehicle needs to be taken for service.
