A square frame has sides that measure 1.55 m when it is at rest. What is the area of the frame when it moves parallel to its sides?

Answer :

Final answer:

The area of the square frame remains unchanged at 2.4025 square meters when it moves parallel to its sides, as the effects of length contraction are negligible at everyday speeds.

Explanation:

To answer the student's question about the area of a moving square frame, we need to understand the concept of length contraction in the field of Physics. According to the theory of special relativity, when an object moves at a high velocity relative to an observer, its length along the direction of motion appears to be shorter than when it is at rest. This phenomenon is known as length contraction. However, for everyday speeds much less than the speed of light, this effect is negligible, and thus the area of the square frame remains the same when it moves parallel to its sides.

The area of a square is calculated as the side length squared. Given that each side is 1.55 meters, the area of the square frame can be calculated as follows:

Area = side × side
Area = 1.55 meters × 1.55 meters

Therefore, the area of the square frame is:

Area = 2.4025 square meters
