Activity 1.1. Simple Activity on Simultaneity
Consider the given illustrations/situations below as reference for this activity. Analyze and explain the perception of the observers below using your understanding of relativity of simultaneity.











Activity 1.2. Resolving Twin Paradox
Deniece is one of the most promising young Physicist in our country. At the age of 20, she participated on a space journey with a speed of .85c leaving her twin brother Liam who facilitated the conduct of the said space exploration. In addition, the space journey took 35 years based on Earth’s time. Based on this situation, identify the age of the twins after Deniece successfully returned to Earth. In addition, describe how time dilation affects aging in the outer space.

Activity 1.3. Shrinking Ship
Danny is driving a spaceship with a length of 60 meters at the speed of .32c and is observed by Susan in the direction relative to her. Based on this situation, identify the perceived length of the space shuttle using the principle of length contraction. In addition, describe what happened to the length of the space shuttle. Moreover, describe what will happen to an object as it reaches the speed of light.
