Question
For each statement select True or False.True/False: The total kinetic energy of a body is limited, since its speed can never exceed c.
True/False: A static body has energy but no kinetic energy.
True/False: The lengths along the direction of motion of moving objects are shorter than when they are at rest.
True/False: The mass of an atom does not change when it emits light.
True/False: Relativistic effects are especially important when speeds are close to the speed of light.
True/False: A moving clock runs slowly
Explanation / Answer
1). False. Kinetic energy can be whatever your budget and technology allows. Mass increase at relativistic speed makes up for the lack of velocity increase. 2True. Kinetic energy is energy of motion. Static bodies aren't moving. 3)True 4). True. The energy used to create the photon comes from an electron changing from a high to a lower energy state. 5).True 6).False. Time passes more slowly in the moving frame of reference.
