A lively image showing two individuals in a train enroute north at a speed of 10 m/s. The passengers are of Black and Hispanic descent respectively, one is a male and the other a female. They are curiously walking 1 m/s towards the southern direction in relation to the train's direction. The surrounding exterior of the moving train signifies a static ground as reference point, with distinct north-bound motion indicating 9 m/s. Remember not to incorporate any written content in the visual representation. Make sure to highlight the universal rule of motion relative to light speed.

Two people are on a train that is moving at 10 m/s north. They are walking 1 m/s south relative to the train. Relative to the ground, their motion is 9 m/s north.

Why are we able to use these motions to describe the motion relative to the ground?

The motion of everything in the Universe besides light can be described in this way.

The people are moving much slower than the speed of light so the ground acts as a frame of reference.

As long as the frame of reference is stationary, all motion can be described in this way.

If one object is moving much slower than the speed of light, its speed can be added to that of another object.

1. Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

2. Both calcium carbonate and sodium carbonate are being produced.
3. The reaction is reversible.
4. 300,000 km/s
5. The people are moving much slower than the speed of light so the ground acts as a frame of reference.

The correct answer is the people are moving much slower than the speed of light so the ground acts as a frame of reference.

thank school balls all of theme are correct. you saved my life. thank you soo much. have a grate day.

School balls is right. I’m in connexus force and motion concepts quick check

lego's answers are 100% :)

Because the motion of everything in the Universe, besides light, can be described in this way. It's like the ground is playing matchmaker, helping us calculate the total motion by combining the speeds. And luckily, the people on the train are moving much slower than the speed of light, so the ground can act as a steady frame of reference without getting motion sickness. So, as long as the ground stays put, we can use these motions to describe their speed relative to the ground. Just make sure the ground doesn't decide to go on a joyride!

We are able to use these motions to describe the motion relative to the ground because the motion of everything in the Universe, except for light, can be described using this approach. It is based on the concept of frames of reference, which is a system of measuring and describing the motion of objects.

In this scenario, the train is moving at 10 m/s north. The two people on the train are walking south relative to the train at a speed of 1 m/s. By using the train as their reference point, their motion relative to the train is in the opposite direction, which is north at a speed of 1 m/s. So, their motion relative to the train is 1 m/s north.

To find their motion relative to the ground, we add their motion relative to the train (1 m/s north) to the motion of the train itself (10 m/s north). This gives us a total motion of 11 m/s north relative to the ground.

You might wonder why we can use the ground as a frame of reference. The reason is that the speed of light is much faster than any typical object's speed, including the train and the people walking. Since the people are moving much slower than the speed of light, the ground can act as a stationary frame of reference for describing their motion.

To summarize, we can use these motions to describe the motion relative to the ground because the people and the train are both moving much slower than the speed of light. As long as the frame of reference is stationary, we can add the speeds of objects moving slower than light to find their total motion relative to that frame of reference.
