## How do you explain time relativity?

In the Special Theory of Relativity, Einstein determined that time is relative—in other words, the rate at which time passes depends on your frame of reference.

## How do you solve relativity problems?

How to Solve Special Relativity Problems

- Draw a Picture. In Special Relativity problems, you relate the observations made by two observers in different reference frames measuring the same thing.
- Select the Relation. There are three key relations for Special Relativity.
- Solve the Problem.
- Understand the Results.

**What are the two basic principles of relativity?**

The theory is based on two fundamental principles: Relativity – The laws of physics do not change. Even for objects moving at inertial, constant speed frames of reference. The speed of light – It is the same for all observers regardless of their relative motion to the source of light.

**Are there any real problems with special relativity?**

Special Relativity Questions & Problems (Answers) 1. If you were on a spaceship travelling at 0.50c away from a star, what speed would the starlight pass you? (The speed of light: 3.00 x 108m/s) 2. Does time dilation mean that time actually passes more slowly in moving references frames or that it only seems to pass more slowly?

### Which is postulate of special relativity does not fit with classical physics?

1. Which of Einstein’s postulates of special relativity includes a concept that does not fit with the ideas of classical physics? Explain. 2. Is Earth an inertial frame of reference? Is the Sun? Justify your response. 3.

### What should the relativistic effect of Γ be?

If relativistic effects are to be less than 3%, then γ must be less than 1.03. At what relative velocity is γ = 1.03? 31. (a) At what relative velocity is γ = 1.50? (b) At what relative velocity is γ = 100? 32. (a) At what relative velocity is γ = 2.00? (b) At what relative velocity is γ = 10.0? 33. Unreasonable Results

**Why are relativistic effects present in cars and airplanes?**

Relativistic effects such as time dilation and length contraction are present for cars and airplanes. Why do these effects seem strange to us? 9. Suppose an astronaut is moving relative to the Earth at a significant fraction of the speed of light.
