Question

Relativity concepts: For each statement select True or False.

For each statement select True or False. The mass of an atom does not change when it emits light. Relativistic effects are especially important when speeds are close to the speed of light. A moving clock runs slowly A static body has energy but no kinetic energy. The total kinetic energy of a body is limited, since its speed can never exceed c. The lengths along the direction of motion of moving objects are shorter than when they are at rest.

Explanation / Answer

a)

False : atoms loses some mass which gets converted into energy in the form of light.

b)

True

c)

True : This is due to Time dilation.

d)

True : for the kinetic energy to be present , the body must have some speed.

e)

False

f)

True : This is due to length contraction effect.
