Question

Can classical physics be used to accurately describe a satellite moving at a speed of $\mathbf{7500}\mathbf{}\mathit{m}\mathbf{/}\mathit{s}$? Explain why or why not.

Short answer

Yes, you can use classical physics for the description of satellites.

Step-by-step solution

Classical Physics

Classical physics deals with the systems that are made up of many particles—for Example- the motion of a car, the falling of a raindrop, etc. When we talk about a car or a raindrop, they are made up of many atoms and hence, a much larger number of fundamental particles. Thus, their motion can easily be explained by classical physics.

Can it explain the satellite?

Just like a car or a raindrop, a Satellite is also made up of a very large number of particles. Thus, a satellite can be described using classical physics. It is traveling with a velocity of $7500m/s$,which is not comparable to the speed of light. Hence, no relativistic effects will be experienced.

Conclusion

Yes, Classical physics can explain with high accuracy the motion of a satellite.
