Question
Select the correct option for the following statements. True, False, Equal To, Greater than, Less than
The length of an object measured by a person moving along the object is ... the length measured by a person at rest with respect to the object.
The speed of light measured by a person moving at a constant speed close to the speed of light is ... the speed measured by a person at rest.
If we travel at the speed of light for 1 year (as measured by us), when we return to Earth we are 1 year older.
If a star is 50,000 light years away, we see it today as it was 50,000 years ago.
Special relativity says that all observers must measure the same time between events.
According to a person at rest, the period of a moving clock is .... the period of an identical clock at rest.
Thank you
Explanation / Answer
The length of an object measured by a person moving along the object is "Less Than" the length measured by a person at rest with respect to the object.
The speed of light measured by a person moving at a constant speed close to the speed of light is "Equal to" the speed measured by a person at rest.
If we travel at the speed of light for 1 year (as measured by us), when we return to Earth we are 1 year older. - True.
If a star is 50,000 light years away, we see it today as it was 50,000 years ago - True.
Special relativity says that all observers must measure the same time between events. - False
According to a person at rest, the period of a moving clock is "Less than" the period of an identical clock at rest.
